SSG-86 Radiation Protection Programmes for the Transport of Radioactive Material

Sekce Odstavec Text
Main 1.1. IAEA Safety Standards Series No. SSR‑6 (Rev. 1), Regulations for the Safe Transport of Radioactive Material, 2018 Edition [1] (hereinafter referred to as ‘the Transport Regulations’) provides a regulatory framework for the safe transport of all types of radioactive material, such as naturally occurring radioactive material; radioactive sources used in academic, industrial and medical applications; nuclear fuel; and radioactive waste. The Transport Regulations cover all facets of safe transport by means of a set of technical and administrative safety requirements, including for the actions of transport organizations1 and competent authorities.
Main 1.2. The fundamental requirements for radiation protection are stated in para. 301 of the Transport Regulations. Paragraph 302 of the Transport Regulations states:
Main 1.3. IAEA Safety Standards Series No. GSR Part 3, Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards [2], establishes radiation protection requirements for planned exposure situations, including the transport of radioactive material. Recommendations on meeting the requirements of GSR Part 3 [2] for occupational radiation protection, including the development of an RPP, are provided in IAEA Safety Standards Series No. GSG‑7, Occupational Radiation Protection [3]. Recommendations on meeting the requirements of GSR Part 3 [2] for public exposures are provided in IAEA Safety Standards Series No. GSG‑8, Radiation Protection of the Public and the Environment [4].
Main 1.4. This Safety Guide provides recommendations on meeting the requirements established in para. 302 of the Transport Regulations for an RPP for the transport of radioactive material. The intended audience for the Safety Guide includes competent authorities, consignors, carriers, consignees and operators of ports (e.g. harbours, seaports, airports). This Safety Guide will also be of interest to the employees of public authorities (e.g. custom authorities, harbour authorities, port authorities, modal authorities) concerning activities associated with the transport of radioactive material that involve radiation exposure.
Main 1.5. The scope of this Safety Guide is the same as in para. 106 of the Transport Regulations: the transport of radioactive material by all modes on land, on water or in the air, including transport that is incidental to the use of the radioactive material.
Main 1.6. This Safety Guide consists of ten sections. Section 2 discusses the objectives and the application of a graded approach to RPPs. Section 3 discusses the scope and provides an overview of the basic elements of an RPP. Sections 4–10 provide recommendations on the elements of an RPP, namely the associated roles and responsibilities, dose assessment and optimization, control of surface contamination, segregation and other protective measures, emergency preparedness and response, training, and the management system.
Main 1.7. Eight annexes are included in this Safety Guide. They include examples to support the development of RPPs, questions that can be used for evaluating the effectiveness of RPPs and an excerpt from the International Maritime Dangerous Goods (IMDG) Code [5] on segregation distances.
Main 2.1. Paragraph 3.49 of GSG‑7 [3] states:
Main 2.2. Paragraph 302.1 of IAEA Safety Standards Series No. SSG‑26 (Rev. 1), Advisory Material for the IAEA Regulations for the Safe Transport of Radioactive Material (2018 Edition) [6], states:
  • To provide for adequate consideration of radiation protection measures in transport;

  • To ensure that the system of radiation protection is adequately applied;

  • To enhance a safety culture in the transport of radioactive material;

  • To provide practical measures to meet these objectives.”

Main 2.3. An RPP is required by para. 302 of the Transport Regulations to incorporate the requirements of paras 301, 303–305, 311 and 562 of the Transport Regulations. Relevant national requirements should also be incorporated into the RPP.
Main 2.4. The RPP may be documented in one or more documents (and may be either a separate programme or part of a facility’s RPP; see para. 3.6) and should be included in the management system of the transport organization (see Section 10).
Main 2.5. General requirements on leadership and management for safety, including establishing, sustaining and continually improving an effective management system, are established in IAEA Safety Standards Series No. GSR Part 2, Leadership and Management for Safety [7]. Guidance on management systems for the safe transport of radioactive material is given in IAEA Safety Standards Series No. TS‑G‑1.4, The Management System for the Safe Transport of Radioactive Material [8].
Main 2.6. An RPP does not usually address arrangements for criticality safety. Recommendations on such arrangements are provided in SSG‑26 (Rev. 1) [6] and IAEA Safety Standards Series No. SSG‑27 (Rev. 1), Criticality Safety in the Handling of Fissile Material [9].
Main 2.7. Paragraph 302.2 of SSG‑26 (Rev. 1) [6] states:
  • Scope of the programme (see paras 302.3–302.5 [of SSG‑26 (Rev. 1) [6]]);

  • Roles and responsibilities for the implementation of the programme (see para. 302.6 [of SSG‑26 (Rev. 1) [6]]);

  • Dose assessment and optimization (see para. 303 of the Transport Regulations);

  • Assessment of surface contamination (see paras 508, 513 and 514 of the Transport Regulations);

  • Segregation and other protective measures (see paras 562.1–562.13 [of SSG‑26 (Rev. 1) [6]]);

  • Emergency response arrangements (see paras 304 and 305 of the Transport Regulations);

  • Training (see paras 311–315 of the Transport Regulations);

  • Management system (see para. 306 of the Transport Regulations).”

Main 2.8. The radiation protection provisions incorporated into an RPP may be diverse and may reflect, for example, regulatory requirements and managerial and operational criteria for radiation protection in the transport of radioactive material. Paragraph 302 of the Transport Regulations states that “The nature and extent of the measures to be employed in the programme shall be related to the magnitude and likelihood of radiation exposure.”
Main 2.9. Paragraph 303 of the Transport Regulations establishes a graded approach to the assessment of occupational exposures, as follows:
  • Is likely to be between 1 and 6 mSv in a year, a dose assessment programme via workplace monitoring or individual monitoring shall be conducted; or

  • Is likely to exceed 6 mSv in a year, individual monitoring shall be conducted.”

Main 2.10. Transport operations involving only a small number of shipments of packages of lower potential radiological hazard should have at least a basic programme for the assessment of occupational exposures, while more significant operations (e.g. transport operations involving diverse types of radioactive material and transport operations with the potential for significant exposures) should have a more comprehensive programme.
Main 2.11. Transport operations that result in low occupational exposures or those organizations that only occasionally transport radioactive material still require an RPP, in accordance with para. 302 of the Transport Regulations.
Main 3.1. An RPP should cover all aspects of transport described in para. 106 of the Transport Regulations, and the associated conditions, including:
  • Routine conditions of transport (incident free);

  • Normal conditions of transport (minor mishaps);

  • Accident conditions of transport.

Main 3.2. The RPP should include the measures needed to meet the requirements of the Transport Regulations for radiation protection, including monitoring provisions. Requirement 24 of GSR Part 3 [2] requires the establishment of an RPP for occupational exposure. However, as stated in para. 3.52 of GSG‑7 [3], “the radiation protection programme could include protection of both workers and the public”. Consistent with para. 302 of the Transport Regulations, which requires that RPPs incorporate the requirements for, inter alia, limitation and optimization of doses to persons (para. 301 of the Transport Regulations), emergency response (paras 304 and 305 of the Transport Regulations) and segregation (para. 562 of the Transport Regulations), all of which may involve public exposure, the RPP for the transport of radioactive material should include the protection of both workers and the public.
Main 3.3. The focus of an RPP for the transport of radioactive material should generally be on transport and handling operations that have the potential to result in radiation exposures or contamination of people, property or the environment. Such operations include the packing, preparation, loading, handling, storage in transit, carriage, intermodal transfer, delivery and unloading of packages of radioactive material, as well as the inspection and maintenance of packaging (if contaminated or containing residual radioactive material).
Main 3.4. An RPP should define and document a systematic framework of controls to be applied by a transport organization, with the primary aim of optimizing radiation protection in the transport of radioactive material. The RPP should be developed and implemented during the pre‑operational stage of the shipment of radioactive material, for example for such transport operations as the selection of an appropriate package type and the scheduling and preparation of packages containing radioactive material. Even if radiation protection has been optimized at the pre‑operational stage, there will still be a need for radiation protection arrangements and their optimization at the various stages of transport operations.
Main 3.5. Transport related operations that do not involve occupational exposure or public exposure (e.g. administrative work; design and manufacture of packaging; repair of packaging that does not involve any radiation exposure) do not need to be covered by an RPP for transport.
Main 3.6. Transport operations such as the packing, preparation, loading, handling, delivery and unloading of packages containing radioactive material often occur at facilities that are subject to regulatory requirements, for example nuclear power plants, nuclear fuel cycle facilities (including uranium mining and processing facilities), isotope production facilities, nuclear medicine departments in hospitals, and industrial facilities that use radioactive sources. Such facilities are required to have their own RPP that applies to their operations (see Requirement 24 of GSR Part 3 [2]), including the on‑site movement of radioactive material. Transport operations associated with these facilities are often within the scope of the facility RPP, and in these cases the facility RPP should have provisions that address the transport activities that take place at the facility; however, in some cases, such transport operations may be covered by a transport specific RPP. See also paras 4.2–4.5.
Main 4.1. The Transport Regulations assign specific roles and responsibilities to transport organizations and competent authorities. This section provides recommendations on these duties and responsibilities in relation to the establishment and implementation of an RPP for the transport of radioactive material.
Main 4.2. Requirement 4 of GSR Part 3 [2] states that “The person or organization responsible for facilities and activities that give rise to radiation risks shall have the prime responsibility for protection and safety.” Therefore, the activities of each transport organization involved with a shipment of radioactive material (e.g. consignors; carriers; operators of harbours, seaports and airports; consignees) are required to be covered by an RPP. These activities should be specified under the scope of the RPP of the organization. It is the responsibility of the management of transport organizations directly involved in the radioactive material transport chain to establish and implement an RPP for their operations. It is unreasonable to assign the duty of establishing an additional RPP to a transport organization (e.g. the consignor) for a transport activity it has no direct control over (i.e. no staff are involved) and for which radiation protection provisions are applied by subsequent transport organizations (e.g. carriers).
Main 4.3. Transport organizations should cooperate to fulfil the objectives of their RPPs. In more complex transport operations (e.g. a transboundary shipment of radioactive material by road, rail, air and sea), this may involve many independent carriers, where each party operates under its own management system (see Section 10), or several transport organizations that perform operations at the same site (e.g. port, airport) involving the same individuals, leading to an accumulation of doses to those individuals.
Main 4.4. The RPP should address interfaces among the different transport organizations. A dedicated carrier may be contracted solely for transport operations by a consignor or consignee, and in such cases the consignor or consignee may have an RPP that covers the carrier’s operations. In such circumstances, the competent authority might not require the carrier to have a separate RPP solely for transport if the relevant consignor or consignee ensures that the radiation protection measures to be followed by the carrier are included in the consignor’s or consignee’s RPP. In the case of shipment under exclusive use of a conveyance or a large freight container (para. 221 of the Transport Regulations), the consignor or consignee, as appropriate, is responsible for ensuring that directions for loading, unloading and shipment are included in the RPP.
Main 4.5. In some cases, a transport organization may prepare shipments at a facility operated by another organization. The transport organization should normally have its own RPP (i.e. for transport), and the facility should also have its own RPP (i.e. for activities it conducts within the facility). The scope of the two RPPs and the interfaces between them should be determined in advance and should be recorded.
Main 4.6. The competent authority may require the consignor, carrier or consignee to evaluate the adequacy of the RPPs of its subcontractors involved in the transport of its consignments of radioactive material. Consignors or other individuals and organizations with relevant experience and expertise, such as transport companies specialized in the organization of shipments of radioactive material, may also assist subcontractors in the development of their own RPPs.
Main 4.7. The management of transport organizations are required to establish safety policies, management systems and organizational arrangements, and provide sufficient resources, to ensure that the objectives of the RPP can be achieved (see Requirements 3 and 6–9 of GSR Part 2 [7]). The management of each transport organization should also identify and document the objectives of the RPP.
Main 4.8. The management system is required to reflect the management’s commitment to radiation protection by means of written policy statements (see para. 4.16 of GSR Part 2 [7]) and by clear support for those with responsibility for radiation protection (see para. 3.3 of GSR Part 2 [7]). The organizational arrangements include specifying and documenting the roles and responsibilities of the individuals involved and the functions to be performed by them (see para. 4.16 of GSR Part 2 [7]).
Main 4.9. Infrastructure, arrangements and resources that may be necessary to achieve the objectives of the RPP include facilities, suitably qualified personnel, equipment, training, feedback mechanisms and the delegation of authority to individuals to perform actions to ensure compliance with regulatory requirements and with managerial and operational procedures. The individuals responsible for managing the RPP and the measures specified in it should be clearly designated and should be given the necessary authority to implement the programme and those measures.
Main 4.10. With regard to the RPP, para. 302 of the Transport Regulations states that “Programme documents shall be available, on request, for inspection by the relevant competent authority.
Main 4.11. Requirement 22 of GSR Part 3 [2] states that “Workers shall fulfil their obligations and carry out their duties for protection and safety.” This requirement reflects the fact that workers contribute, by their own actions, to protection for themselves and others at work [3]. In addition, para. 3.83(a) of GSR Part 3 [2] states that workers “Shall follow any applicable rules and procedures for protection and safety as specified by the employer, registrant or licensee”.
Main 4.12. Some tasks associated with the development or implementation of an RPP may be performed by a qualified expert2 with relevant expertise (e.g. radiation protection, quality management). However, the overall responsibility for ensuring radiation protection and for compliance with regulatory requirements remains with the management of the transport organization.
Main 4.13. Paragraph 307 of the Transport Regulations states that “The competent authority shall assure compliance with these Regulations.” To assure compliance with the requirements for an RPP in para. 302 of the Transport Regulations, various activities should be implemented by the competent authority, for example establishment of regulations and guidance concerning RPPs; inspections of management systems and transport operations; the implementation of enforcement actions, where appropriate; participation in training (i.e. providing training material, holding training courses and making personnel from the competent authority available to provide presentations at training courses); and distribution of information.
Main 4.14. Recommendations on the development and maintenance of compliance assurance programmes are provided in IAEA Safety Standards Series No. SSG‑78, Compliance Assurance for the Safe Transport of Radioactive Material [10]. Furthermore, guidance, procedures and checklists that may be used by a competent authority in relation to inspections of management systems, consignors, carriers and maintenance operations, including RPPs, are provided in annexes III–VII and IX to SSG‑78 [10]. This information can be adapted and applied to other organizations involved in the transport of radioactive material.
Main 4.15. Paragraph 308 of the Transport Regulations states that “The relevant competent authority shall arrange for periodic assessments of the radiation doses to persons due to the transport of radioactive material, to ensure that the system of protection and safety complies with GSR Part 3 [2].” Examples of such an assessment are presented in Ref. [11] (for transport by road and rail), Ref. [12] (for transport by sea) and Ref. [13] (for transport by air).
Main 5.1. A first step in establishing an RPP is the conduct of a prior radiological evaluation of the transport operations to be performed. Paragraph 3.55 of GSG‑7 [3] states:
  • The sources of routine exposure and reasonably foreseeable potential exposure, such as surface contamination, airborne contamination and sources of external radiation.

  • The nature and magnitude of exposures in normal operations.

  • The nature, likelihood and magnitude of potential exposures.…

  • The measures for protection and safety that are necessary to implement the optimization process.

  • Appropriate monitoring systems”.

Main 5.2. Paragraph 3.56 of GSG‑7 [3] states:
  • Use of workplace monitoring. This method can give a good assessment of the doses that workers will receive, provided that the radiological conditions in the workplace are reasonably predictable over a long period (at least for several months). Workplace monitoring should be repeated at appropriate intervals, and certainly when the working conditions change significantly.

  • Use of data from the scientific literature and information from comparable facilities. Some dose values are given in the literature for various workplace situations. These can, in principle, be used to judge whether monitoring is needed.

  • Use of simulations. Numerical simulations can be powerful and can provide information instantly on the parameters that influence doses that would be received in given exposure situations. The results of simulations should be verified by measurement.

  • Use of confirmatory measurements. Performing confirmatory measurements with personal dosimeters can help to determine whether individual monitoring is needed.”

Main 5.3. With regard to transport operations, the prior radiological evaluation should take into account the following information:
  • The radionuclides, the activity levels, the physical and chemical form of radioactive material, the package type and category being transported, and the dose rates around packages and in and around vehicles.

  • The magnitude and likelihood of occupational exposures and public exposures arising from routine (incident free), normal (minor mishaps) and accident conditions of transport, taking into account the following: use of overpacks or freight containers; ad hoc stops, parking and delays due to traffic conditions during land transport; the necessity of storage in transit; the use of different modes of transport or conveyances and stowage within the conveyance; and specific handling procedures (e.g. for small packages or packages that are handled remotely). If applicable, this may also include consideration of potential exposures arising from failures to correctly assemble and use packages.

  • The number of workers involved and their activities that might involve exposure to radiation.

  • The duration and frequency of operations.

  • The distance between workers and packaged or unpackaged radioactive material.

  • The distance between members of the public and packaged or unpackaged radioactive material.

  • Shielding and other protective measures implemented to optimize radiation protection.

Main 5.4. A programme of radiation monitoring will be a fundamental part of any RPP. Paragraph 3.98 of GSG‑7 [3] states:
  • Assessing the exposure of workers and demonstrating compliance with regulatory requirements.

  • Confirming the effectiveness of working practices (e.g. the adequacy of supervision and training) and engineering standards.

  • Determining the radiological conditions in the workplace, whether these are under adequate control and whether operational changes have improved or worsened the situation.

  • Evaluating and improving operating procedures from a review of the collected monitoring data for individuals and groups. Such data may be used to identify both good and bad features of operating procedures and design characteristics, and thereby contribute to the development of safer working practices in relation to radiation.

  • Providing information that can be used to enable workers to understand how, when and where they are exposed, and to motivate them to take steps to reduce their exposure.

  • Providing information for the evaluation of doses in the event of accidental exposures.”

Main 5.5. All transport organizations, including consignors, carriers and consignees, have some responsibilities for workplace, package and individual monitoring, depending on the radiological characteristics of the transport operations they undertake.
Workplace monitoring and package monitoring 5.6. Workplace monitoring comprises measurements made in the working environment as appropriate to the transport organization and the interpretation of such measurements. Routine monitoring in the workplace may be performed both to demonstrate that the work conditions remain satisfactory and to meet regulatory requirements. Additionally, the results of the monitoring may be used to assess the radiation exposures to workers. The measurements can be made anywhere transport operations are undertaken, such as areas (including conveyances) in which the packing, preparation, loading, handling, carriage, storage in transit, intermodal transfer, delivery, unloading and inspection of packages of radioactive material, and the maintenance of packaging for radioactive material, are performed. Such measurements comprise monitoring for external radiation, for surface contamination and in rare cases (e.g. the loading of drums with uranium oxide concentrate) for air contamination.
Workplace monitoring and package monitoring 5.7. As described in para. 2.9, workplace monitoring may be used in the dose assessment programme for workers where occupational exposures are likely to be between 1 and 6 mSv in a year.
Workplace monitoring and package monitoring 5.8. The nature and frequency of workplace monitoring should first be determined on the basis of the prior radiological evaluation and should be specified in the RPP, then updated if necessary to take into account actual results of workplace monitoring. The RPP should include a procedure for assigning doses to workers based on the results of workplace monitoring.
Workplace monitoring and package monitoring 5.9. Routine monitoring at the surface of and at a certain distance from packages containing radioactive material should be specified in the RPP. This monitoring should confirm compliance with the limits for dose rate and surface contamination specified in the Transport Regulations and should confirm that the dose rates and contamination levels are consistent with the assumptions in the prior radiological evaluation. The nature and frequency of the monitoring, which should be based on the prior radiological evaluation, should be specified.
Workplace monitoring and package monitoring 5.10. The equipment to be used for workplace monitoring and for package monitoring should be suitable for the types of radiation encountered and should be regularly calibrated. This calibration should be traceable to recognized national standards. Further recommendations on the establishment of a workplace monitoring programme are provided in GSG‑7 [3].
Individual monitoring of workers involved in the transport of radioactive material 5.11. Individual monitoring is based on measurements made using equipment worn by individual workers, such as personal dosimeters for external exposure or personal air samplers for the rare cases in which internal exposure is assessed (e.g. during the packing, preparation, loading and unloading of consignments containing naturally occurring radioactive material associated with mining and processing; during emergency situations involving potential airborne activity). Individual monitoring is useful in ensuring that radiation exposures are as low as reasonably achievable and for demonstrating compliance with dose limits. Individual monitoring allows a value of external or internal dose to be assigned to an individual. Where an individual monitoring programme is necessary, it should be part of the RPP.
Individual monitoring of workers involved in the transport of radioactive material 5.12. As described in para. 2.9, individual monitoring may be used in the dose assessment programme for workers where occupational exposures are likely to be between 1 and 6 mSv in a year. Individual monitoring should be used for the assessment of occupational doses in this range, unless impracticable. Individual monitoring is required to be undertaken where occupational exposures are likely to exceed 6 mSv in a year (see para. 303(b) of the Transport Regulations).
Individual monitoring of workers involved in the transport of radioactive material 5.13. Personal dosimeters used for individual monitoring should be suitable for the types of radiation encountered (in most cases, gamma radiation, and sometimes neutron radiation) and should be calibrated to meet the appropriate performance standards. The placement of personal dosimeters should take into account the radiation fields that are present (e.g. consideration should be given to the placement of dosimeters on drivers of vehicles to ensure the reliable assessment of individual exposure from radiation emitted from radioactive material behind them). The complementary use of direct‑reading or audible alarming personal dosimeters should be considered in situations in which external exposures above specified levels might occur. Further recommendations on the establishment of an individual monitoring programme are provided in GSG‑7 [3].
Individual monitoring of workers involved in the transport of radioactive material 5.14. Data on airborne radioactive material and surface contamination may be used to estimate possible internal doses. Internal exposures can be assessed through methods such as measurements of radionuclides in the whole body, measurements of radionuclides in biological samples or measurements of activity concentrations in air samples collected using personal air samplers worn by the worker. Further recommendations on the assessment of internal occupational exposure are provided in GSG‑7 [3].
Records of workplace monitoring and individual monitoring 5.15. Paragraph 303 of the Transport Regulations states that “When workplace monitoring or individual monitoring is conducted, appropriate records shall be kept.” Requirements for keeping records of occupational exposure are established in paras 3.103–3.107 of GSR Part 3 [2], and recommendations are provided in paras 7.251–7.273 of GSG‑7 [3].
Records of workplace monitoring and individual monitoring 5.16. Paragraph 3.105 of GSR Part 3 [2] states:
  • Information on the general nature of the work in which the worker was subject to occupational exposure;

  • Information on dose assessments, exposures and intakes at or above the relevant recording levels specified by the regulatory body and the data upon which the dose assessments were based;

  • When a worker is or has been exposed while in the employ of more than one employer, information on the dates of employment with each employer and on the doses, exposures and intakes in each such employment;

  • Records of any assessments made of doses, exposures and intakes due to actions taken in an emergency or due to accidents or other incidents, which shall be distinguished from assessments of doses, exposures and intakes due to normal conditions of work and which shall include references to reports of any relevant investigations.”

Records of workplace monitoring and individual monitoring 5.17. Paragraph 7.252 of GSG‑7 [3] states:
  • Demonstrating the effectiveness of the optimization process;

  • Providing data for the compilation of dose distributions;

  • Evaluating trends in exposure and thus providing the information necessary for the evaluation of the radiation protection programme;

  • Developing effective procedures and programmes for monitoring;

  • Providing exposure data from new medical procedures and programmes;

  • Providing data for epidemiological and research studies;

  • Providing information that may be necessary for litigation related purposes or for workers’ compensation claims, which can arise years after the actual or claimed exposure.”

Records of workplace monitoring and individual monitoring 5.18. Workplace monitoring and/or individual monitoring are required to form the basis of the dose assessment programme for workers who receive occupational exposures above 1 mSv in a year (see para. 303 of the Transport Regulations). However, other methods of estimating external exposures (e.g. as outlined in paras 5.19–5.26) are needed, for example for occupational exposures below 1 mSv in a year and for public exposure. In addition, these methods can be used as part of the prior radiological evaluation, which is performed before the results of workplace monitoring or individual monitoring are available.
Records of workplace monitoring and individual monitoring 5.19. Paragraph 302.5 of SSG‑26 (Rev. 1) [6] states that “The external dose rates from excepted packages and category I‑WHITE label packages are sufficiently low as to be safe to handle without restriction, and a dose assessment is therefore unnecessary.” For other packages, a fundamental consideration in any estimation of external dose is the dose rates associated with packages and conveyances, which may range up to specified maximum values depending on the conditions of transport. The values relating to dose rate and transport index (TI) specified in the Transport Regulations for different package types and categories, which apply also to overpacks and freight containers, are shown in Table 1.
Estimating exposures from the transport of radioactive material using published data 5.20. Various publications are available that give the results of dose assessments that have been performed for different modes of transport and for different types of radioactive material, for example as follows:
  • Several publications give results of assessments of doses to workers and to members of the public from the transport of radioactive material by specific modes of transport, for example Refs [11–14].

  • The results of a coordinated research project that included the assessment of doses to workers and to members of the public from the transport of naturally occurring radioactive material are documented in Ref. [15].

  • An assessment of the doses to workers and to members of the public from the transport of radioactive waste from a 99Mo production facility is documented in Ref. [16].

  • An assessment of the doses to workers and to members of the public from nuclear fuel cycle material, including fresh fuel, spent fuel and high level waste, and for various modes of transport, is summarized in Ref. [17].

  • Information about dose assessments relating to the transport of spent nuclear fuel is provided in Ref. [18]. Information about dose assessments for workers involved in the transport of spent nuclear fuel and high level waste by rail is provided in Ref. [19].

  • Data on doses to workers from the transport and handling of large numbers of packages for medical use and for industrial use are provided in Ref. [20].

Estimating exposures from the transport of radioactive material using the transport index 5.21. The sum of the TIs for the packages handled by workers undertaking specific transport operations may be used as a general indicator of external exposures, for example as follows:
  • To establish a relationship between the sum of the TIs for the packages transported and the external exposures received;

  • To determine the external exposure associated with the transport of packages with a unit TI that is representative of good practices in a specific transport operation;

  • To define a threshold for the sum of the TIs for the packages handled in a year, below which the occupational exposures are likely to be below 1 mSv in a year.

Estimating exposures from the transport of radioactive material using the transport index 5.22. Information from several studies has indicated a general correlation between the sum of the TIs for the packages handled and occupational exposure, with higher TIs resulting in higher doses to workers [11, 14, 21]. In cases for which a reproducible correlation between TI and occupational exposure for specific transport operations can be demonstrated, this correlation can be used to establish a screening level, in terms of the sum of the TIs for the packages handled, below which workplace monitoring or individual monitoring would not be necessary. When the characteristics of the transport operations change in a way that might result in an increase in occupational exposure, the screening level should be reassessed.
Estimating exposures from the transport of radioactive material using the transport index 5.23. By taking into account the dose rate limits of the different package categories (see Table 1), it is possible to calculate the number of packages that could be transported under normal conditions of transport before occupational exposures are likely to exceed 1 mSv in a year. Table 2 provides estimates of the number of packages of each category that could be handled in a year before a worker would receive an external exposure exceeding 1 mSv in a year. The numbers are based on the maximum dose rate expected from a package in each category, except as specified in footnotes a and b in Table 2 for the surface dose rate.
Estimating exposures from the transport of radioactive material using the transport index 5.24. In using the results in Table 2, allowance should be made for the occurrence of unforeseen events in which the dose received is more than expected based on the scenarios stated in Table 2 (e.g. longer exposure time, shorter distance). In such a case, the exposure received should be evaluated to determine whether continued use of the numbers in Table 2 is appropriate.
Estimating exposures from the transport of radioactive material using the transport index 5.25. The external dose rates from excepted packages are so low that occupational exposures are not expected to exceed 1 mSv in a year under routine conditions of transport.
Estimating exposures from the transport of radioactive material using analysis by computer code 5.26. In some cases, occupational exposures and public exposures can be estimated using computer codes such as RADTRAN [22], Intertran [23], RISKIND [24], MicroShield [25], MCNP [26], SCALE Code System [27] or HotSpot Health Physics Codes [28]. Any computer codes used should be validated to be used in such an application.
Estimating exposures from the transport of radioactive material using analysis by computer code 5.27. Paragraph 301 of the Transport Regulations states that “Doses to persons shall be below the relevant dose limits.” Dose limits for occupational exposure and public exposure are established in schedule III of GSR Part 3 [2].
Estimating exposures from the transport of radioactive material using analysis by computer code 5.28. Paragraph 1.15 of GSR Part 3 [2] states:
Estimating exposures from the transport of radioactive material using analysis by computer code 5.29. In accordance with the application of a graded approach, for transport operations that give rise to low levels of occupational exposure, only a basic implementation of the optimization principle is likely to be necessary.
Estimating exposures from the transport of radioactive material using analysis by computer code 5.30. Efforts by transport organizations to optimize protection may involve various measures for radiation protection in the use, handling, carriage and delivery of packages containing radioactive material. Such arrangements may include the following:
  • Reviews of individual and collective doses, and comparison with the results of the prior radiological evaluation to identify any problem areas;

  • Application of suitable segregation distances;

  • Adequate shielding arrangements;

  • Specific stowing, loading, unloading and tie‑down instructions for packages with high TIs;

  • Restrictions on access to areas with high dose rates;

  • Implementation of work schedules designed to optimize occupational exposures;

  • Use of equipment for movement and lifting of packages to reduce exposure time and/or increase distance between workers and packages;

  • Implementation of driving and routing restrictions (depending on the road conditions and the weather).

Estimating exposures from the transport of radioactive material using analysis by computer code 5.31. Paragraph 3.93 of GSR Part 3 [2] states:
  • Engineered controls;

  • Administrative controls;

  • Personal protective equipment.”

Estimating exposures from the transport of radioactive material using analysis by computer code 5.32. Dose constraints are an important feature of the optimization of protection. Dose constraints for workers are operations related values of individual dose that should reflect what is achievable by the application of good practices. Dose constraints should be set at some fraction of the dose limit. A benchmark for an appropriate dose constraint is the level of individual dose that is likely to be incurred in well managed transport operations. Dose constraints for workers are required to be established and used by transport organizations (see para. 3.25 of GSR Part 3 [2]). Dose constraints for public exposure are established or approved by the competent authority. In setting dose constraints for public exposure, exposures due to other sources should be taken into account. Dose constraints can be developed for specified tasks. Dose constraints need not be established where operations already result in insignificant doses. Operational limits and conditions (i.e. that bound operational parameters) intended to contribute to the control of radiation exposure should not be confused with dose constraints.
Estimating exposures from the transport of radioactive material using analysis by computer code 5.33. Paragraph 1.15 of GSR Part 3 [2] states that “Optimization is a prospective and iterative process that requires both qualitative and quantitative judgements to be made.” Therefore, as part of the establishment or revision of the RPP, information about transport operations, radiation measurements and dose assessments should be analysed to ensure that protection is optimized. In addition to routine and normal conditions of transport, information from accident conditions should also be reviewed. Any doses, dose rates or levels of surface or airborne contamination that are greater than expected should be analysed to determine their causes, and corrective actions should be implemented as appropriate.
Estimating exposures from the transport of radioactive material using analysis by computer code 6.1. Paragraph 508 of the Transport Regulations states:
  • 4 Bq/cm2 for beta and gamma emitters and low toxicity alpha emitters;

  • 0.4 Bq/cm2 for all other alpha emitters.

Estimating exposures from the transport of radioactive material using analysis by computer code 6.2. Many packages that contain radioactive material have no contamination on their outer surfaces; for other packages, contamination needs to be removed to ensure that the levels are as low as practicable and do not exceed the limits specified in para. 508 of the Transport Regulations. Strategies for the management of surface contamination include the design of facilities and activities to prevent the outer surfaces of packages from becoming contaminated, contamination monitoring of packages, decontamination and the application of other protective measures.
Estimating exposures from the transport of radioactive material using analysis by computer code 6.3. Packages that are loaded under water, such as those that transport spent nuclear fuel, are more likely to have surface contamination than other packages. Consequently, more intensive monitoring for surface contamination is needed for spent nuclear fuel casks than for the majority of other packages containing radioactive material.
Estimating exposures from the transport of radioactive material using analysis by computer code 6.4. Paragraph 512 of the Transport Regulations states:
Estimating exposures from the transport of radioactive material using analysis by computer code 6.5. Periodic monitoring for surface contamination on packages (including empty packages), overpacks, freight containers, components, equipment, conveyances and workers should also be conducted, as appropriate. Monitoring programmes for surface contamination can assist in detecting loss of containment or deviations from good operating procedures and can provide information for monitoring programmes for possible internal exposures. The frequency of monitoring should be implemented in accordance with a graded approach that takes into account the potential for surface contamination in transport operations.
Estimating exposures from the transport of radioactive material using analysis by computer code 6.6. The arrangements and criteria for controlling (fixed and non‑fixed) surface contamination on packages, conveyances and equipment within a transport organization should be described in the RPP, and an outline of the type and extent of the contamination monitoring programme should be provided.
Estimating exposures from the transport of radioactive material using analysis by computer code 6.7. Further recommendations on establishing a contamination monitoring programme, including the selection of monitoring techniques and monitoring equipment, are provided in paras 9.34–9.41 of GSG‑7 [3].
Estimating exposures from the transport of radioactive material using analysis by computer code 7.1. Occupational exposures and public exposures from the transport of radioactive material can be reduced by the segregation of packages from persons and by the application of other protective measures. A description of the arrangements for the segregation of packages from persons and other protective measures should be included in the RPP. Recommendations on the segregation of packages, the restriction of exposure times, the use of shielding and the concept of controlled and supervised areas are provided in the following paragraphs.
Estimating exposures from the transport of radioactive material using analysis by computer code 7.2. The Transport Regulations establish requirements for the segregation of packages that include the dose criteria to be used for the calculation of segregation distances. Specifically, para. 562 of the Transport Regulations states:
  • From workers in regularly occupied working areas by distances calculated using a dose criterion of 5 mSv in a year and conservative model parameters;

  • From members of the public in areas where the public has regular access by distances calculated using a dose criterion of 1 mSv in a year and conservative model parameters”.

Estimating exposures from the transport of radioactive material using analysis by computer code 7.3. Paragraph 563 of the Transport Regulations states:
Estimating exposures from the transport of radioactive material using analysis by computer code 7.4. Example calculations for establishing minimum segregation distances are provided in appendix III to SSG‑26 (Rev. 1) [6]. The International Maritime Organization has established two methods for satisfying segregation requirements for transport by sea, as illustrated in Annex VIII to this Safety Guide, which is an excerpt from Ref. [5].
Estimating exposures from the transport of radioactive material using analysis by computer code 7.5. Segregation distances that correspond to the total TI of a consignment have historically been presented in segregation tables developed for different modes of transport (see appendix III to SSG‑26 (Rev. 1) [6] and Annex VIII to this Safety Guide). Assessments of exposures during air transport [13, 14] and sea transport [12] have shown that the use of such segregation tables has resulted in public exposures well below dose limits and doses to workers not involved in direct handling that are below 1 mSv in a year. However, the use of segregation distances does not in itself ensure that protection is optimized (see paras 5.28–5.33).
Estimating exposures from the transport of radioactive material using analysis by computer code 7.6. With regard to the incorporation of segregation measures into an RPP, consideration should also be given to segregation from undeveloped photographic film and other dangerous goods (see para. 562(c) and (d) of the Transport Regulations). If applicable, requirements for the spacing of packages containing fissile material from one another (see paras 568 and 569 of the Transport Regulations) should also be taken into account (see also para. I–22 of Annex I to this Safety Guide).
Estimating exposures from the transport of radioactive material using analysis by computer code 7.7. Work processes should be evaluated and adjusted to reduce the amount of time that workers are present in radiation fields to reduce their radiation exposure. Examples of adjustments to work processes are as follows:
  • Preparing transport documents in a low dose rate area instead of near the package(s);

  • Performing dose rate measurements at the package surface and at 1 m from the surface of the package by remote means;

  • Using mechanical means such as trolleys or carts to move packages to and from a conveyance instead of carrying individual packages against the body;

  • Planning work processes so that a conveyance can be loaded or unloaded in the minimum amount of time.

Estimating exposures from the transport of radioactive material using analysis by computer code 7.8. In some cases, it may be reasonably practicable to reduce the exposure of workers by installing shielding, for example between the driver and the cargo area on a conveyance, or between work areas and package storage or loading or unloading areas in a facility.
Estimating exposures from the transport of radioactive material using analysis by computer code 7.9. Where possible, groups of packages should be arranged, both in storage areas and in conveyances, so that the packages giving rise to higher dose rates are farthest from workers, so as to increase the segregation distance (see paras 7.2–7.6) and use the packages emitting lower dose rates to provide additional shielding. The arrangement of packages based on the optimization of radiation protection should not compromise non‑radiation‑related aspects of transport safety.
Estimating exposures from the transport of radioactive material using analysis by computer code 7.10. A controlled area is defined in GSR Part 3 [2] as “A defined area in which specific protection measures and safety provisions are or could be required for controlling exposures or preventing the spread of contamination in normal working conditions, and preventing or limiting the extent of potential exposures.” A supervised area is defined in GSR Part 3 [2] as “A defined area not designated as a controlled area but for which occupational exposure conditions are kept under review, even though specific protection measures or safety provisions are not normally needed.” Requirements for controlled areas and supervised areas are established in paras 3.88–3.92 of GSR Part 3 [2], and associated recommendations are provided in GSG‑7 [3].
Estimating exposures from the transport of radioactive material using analysis by computer code 7.11. The area around a moving conveyance is not normally designated as a controlled area or supervised area, but areas within a conveyance might be considered as such by applying measures similar to those that are applicable in a controlled area or in a supervised area. For storage in transit, controlled areas and supervised areas are commonly designated. However, for scheduled and non‑scheduled stops and overnight stops during road transport, such areas are not normally designated. Instead, other measures should be implemented, such as parking a vehicle carrying a package containing radioactive material away from areas that are regularly occupied by members of the public. If a stop occurs at an authorized facility (e.g. at a nuclear facility), the applicable requirements of that facility should be observed.
Estimating exposures from the transport of radioactive material using analysis by computer code 7.12. Paragraph 566(b) of the Transport Regulations states:
Estimating exposures from the transport of radioactive material using analysis by computer code 7.13. The RPP may specify a maximum dose rate for the driver’s compartment that is based on an estimated amount of time that the driver will be present. The RPP should also take into account any relevant national requirements (e.g. in some States, a maximum dose rate for the driver’s compartment of 20 μSv/h has been stipulated).
Estimating exposures from the transport of radioactive material using analysis by computer code 8.1. Compliance with the requirements established in the Transport Regulations ensures a high level of safety for the transport of radioactive material. However, emergencies involving the transport of radioactive material may happen. Paragraph 304 of the Transport Regulations recognizes the importance of advance planning and preparation to provide a sufficient and safe response to any such emergencies. For this purpose, it is necessary that all transport organizations and relevant national or international organizations establish appropriate emergency plans and procedures relevant to their own activities and responsibilities and that these plans and procedures are followed in the event of an emergency involving the transport of radioactive material. Thus, a description of applicable arrangements and instructions concerning emergency preparedness and response should be included in the RPP.
Estimating exposures from the transport of radioactive material using analysis by computer code 8.2. Requirements for an adequate level of preparedness and response for a nuclear or radiological emergency3, including an emergency involving the transport of radioactive material (emergency preparedness category IV), are established in IAEA Safety Standards Series No. GSR Part 7, Preparedness and Response for a Nuclear or Radiological Emergency [30].
Estimating exposures from the transport of radioactive material using analysis by computer code 8.3. Paragraph 1.4 of IAEA Safety Standards Series No. SSG‑65, Preparedness and Response for a Nuclear or Radiological Emergency Involving the Transport of Radioactive Material [31], states:
Estimating exposures from the transport of radioactive material using analysis by computer code 8.4. In accordance with para. 302 of the Transport Regulations, the RPP is required to incorporate the requirements for emergency response stated in paras 304 and 305 of the Transport Regulations. Paragraph 305 of the Transport Regulations states:
Estimating exposures from the transport of radioactive material using analysis by computer code 8.5. Paragraph 304 of the Transport Regulations states:
Estimating exposures from the transport of radioactive material using analysis by computer code 8.6. Recommendations on preparedness and response for a nuclear or radiological emergency involving the transport of radioactive material are provided in SSG‑65 [31].
Estimating exposures from the transport of radioactive material using analysis by computer code 8.7. Paragraph 3.1 of GSR Part 7 [30] states:
Estimating exposures from the transport of radioactive material using analysis by computer code 8.8. Paragraph 2.17 of SSG‑65 [31] states:
Estimating exposures from the transport of radioactive material using analysis by computer code 8.9. Paragraph 6.18 of GSR Part 7 [30] states:
  • A ‘concept of operations’37 for emergency response is developed at the beginning of the preparedness stage.

  • Emergency plans and procedures are prepared and, as appropriate, approved for any facility or activity, area or location that could give rise to an emergency warranting protective actions and other response actions.

Estimating exposures from the transport of radioactive material using analysis by computer code 8.10. Paragraph 3.2 of GSR Part 7 [30] states:
  • To regain control of the situation and to mitigate consequences;

  • To save lives;

  • To avoid or to minimize severe deterministic effects;

  • To render first aid, to provide critical medical treatment and to manage the treatment of radiation injuries;

  • To reduce the risk of stochastic effects;

  • To keep the public informed and to maintain public trust;

  • To mitigate, to the extent practicable, non‑radiological consequences;

  • To protect, to the extent practicable, property and the environment;

  • To prepare, to the extent practicable, for the resumption of normal social and economic activity.”

Estimating exposures from the transport of radioactive material using analysis by computer code 8.11. Paragraph 304 of the Transport Regulations states:
Estimating exposures from the transport of radioactive material using analysis by computer code 8.12. Emergency workers may include first responders, radiological assessors4, and workers associated with carriers and consignors. Requirements for protecting emergency workers and helpers are established in paras 5.49–5.61 of GSR Part 7 [30]. Recommendations and guidance on the protection of emergency workers and helpers are provided in IAEA Safety Standards Series No. GSG‑2, Criteria for Use in Preparedness and Response for a Nuclear or Radiological Emergency [32], and recommendations specific to emergency workers relevant to the transport of radioactive material are provided in SSG‑65 [31].
Estimating exposures from the transport of radioactive material using analysis by computer code 9.1. The successful application of the Transport Regulations can only be achieved by properly planned and implemented initial training and periodic retraining programmes for all individuals involved in the transport of radioactive material. These training programmes should be described in the RPP.
Estimating exposures from the transport of radioactive material using analysis by computer code 9.2. In accordance with para. 302 of the Transport Regulations, the RPP is required to meet the requirements of para. 311 of the Transport Regulations, which states:
Estimating exposures from the transport of radioactive material using analysis by computer code 9.3. Paragraph 311.1 of SSG‑26 (Rev. 1) [6] states:
Estimating exposures from the transport of radioactive material using analysis by computer code 9.4. Paragraph 311.2 of SSG‑26 (Rev. 1) [6] states:
Estimating exposures from the transport of radioactive material using analysis by computer code 9.5. As stated in para. 313 of the Transport Regulations, persons who are directly involved in the transport of radioactive material are required to receive three types of training, as follows:
  • General awareness/familiarization training:

    1. Each person shall receive training designed to provide familiarity with the general provisions of these Regulations.

    2. The general awareness/familiarization training shall include a description of the categories of radioactive material; labelling, marking, placarding and packaging and segregation requirements; the purpose and content of the radioactive material transport document; and the available emergency response documents.

  • Function specific training: Each person shall receive detailed training concerning specific radioactive material transport requirements that are applicable to the function that person performs.

  • Safety training: Commensurate with the risk of exposure in the event of a release, and with the functions performed, each person shall receive training on:

    1. Methods and procedures for avoidance of accident conditions during transport, such as proper use of package handling equipment and appropriate methods of stowage of radioactive material.

    2. Available emergency response information and how to use it.

    3. General hazards presented by the various categories of radioactive material and how to prevent exposure to those hazards, including, if appropriate, the use of personal protective clothing and equipment.

    4. Procedures to be immediately followed in the event of an unintentional release of radioactive material, including any emergency response procedures for which the person is responsible and personal protection procedures to be followed.”

  • Each person shall receive training designed to provide familiarity with the general provisions of these Regulations.

  • The general awareness/familiarization training shall include a description of the categories of radioactive material; labelling, marking, placarding and packaging and segregation requirements; the purpose and content of the radioactive material transport document; and the available emergency response documents.

  • Methods and procedures for avoidance of accident conditions during transport, such as proper use of package handling equipment and appropriate methods of stowage of radioactive material.

  • Available emergency response information and how to use it.

  • General hazards presented by the various categories of radioactive material and how to prevent exposure to those hazards, including, if appropriate, the use of personal protective clothing and equipment.

  • Procedures to be immediately followed in the event of an unintentional release of radioactive material, including any emergency response procedures for which the person is responsible and personal protection procedures to be followed.”

Estimating exposures from the transport of radioactive material using analysis by computer code 9.6. Paragraph 314 of the Transport Regulations states that “Records of all safety training undertaken shall be kept by the employer and made available to the employee if requested.”
Estimating exposures from the transport of radioactive material using analysis by computer code 9.7. Some workers involved in the transport of radioactive material may have received training in radiological protection for reasons other than the transport of radioactive material (e.g. as nuclear plant workers or isotope laboratory staff). In such cases, some of this training may be deemed sufficient to satisfy at least part of the training needs that form part of the RPP for the transport of radioactive material.
Estimating exposures from the transport of radioactive material using analysis by computer code 9.8. Carriers will usually be expected to provide specific training in accordance with the requirements of the applicable modal regulations.
Estimating exposures from the transport of radioactive material using analysis by computer code 9.9. The training of workers for the transport of radioactive material should be oriented towards their job functions and work environment. A graded approach should be applied, in which the amount, type, level of detail and frequency of training is commensurate with the nature of the hazards and the type and complexity of the workers’ duties associated with the transport of radioactive material.
Estimating exposures from the transport of radioactive material using analysis by computer code 10.1. Paragraph 228 of the Transport Regulations defines a management system as “a set of interrelated or interacting elements for establishing policies and objectives and enabling the objectives to be achieved in an efficient and effective manner.” Management systems apply to all activities within the scope of the Transport Regulations; therefore, the RPP, including its development and implementation, is part of the management system. All elements of a management system apply to the RPP, such as its organization, procedures for controlling documents and records, human resources and training considerations, process controls, design control, purchasing procedures (including traceability), inspection procedures, measurement and test control, processes for servicing equipment, the performance of self‑assessments and independent assessments, processes for identifying non‑conformances, and corrective and preventive actions.
Estimating exposures from the transport of radioactive material using analysis by computer code 10.2. Requirements for establishing, applying and continuously improving a management system are established in GSRPart2 [7], and associated recommendations are provided in IAEA Safety Standards Series No. GS‑G‑3.1, Application of the Management System for Facilities and Activities [33]. Recommendations specific to management systems for the transport of radioactive material are provided in TS‑G‑1.4 [8], and further recommendations are provided in paras 306.1–306.5 of SSG‑26 (Rev. 1) [6].

Estimating exposures from the transport of radioactive material using analysis by computer code I–1. This annex presents an example outline of the contents of a generic radiation protection programme (RPP). For each element, information and example text is provided that could be used in developing a specific RPP.
Estimating exposures from the transport of radioactive material using analysis by computer code I–2. The scope of the work covered by the RPP would be included; for example, ‘The scope of this RPP covers the transport and storage in transit of radioactive material but does not include criticality aspects.’ The scope may also include a brief description of the operations, such as ‘This RPP covers the transport of radiography sources.’ Further details on the scope of the transport operations could be included as appropriate.
Estimating exposures from the transport of radioactive material using analysis by computer code I–3. The roles and responsibilities in the organization may, for example, be specified as follows:
  • Training of workers and implementation of proper working procedures;

  • Assessment of worker exposures, if necessary, by individual monitoring or workplace monitoring;

  • Emergency procedures.’

  • Complete transport documents;

  • Measure dose rates and contamination and determine transport index;

  • Complete and apply package labels;

  • Load packages onto the vehicle;

  • Segregate packages;

  • Implement emergency procedures, if appropriate.

Estimating exposures from the transport of radioactive material using analysis by computer code I–4. A prior radiological evaluation (see paras 5.1–5.3) is necessary to determine the level of individual exposure (including potential exposures) and to determine the monitoring programme. Worked examples are given below. The prior radiological evaluation needs to be made on the basis of the following:
  • The number and type of packages;

  • The category and the transport index (TI) of packages;

  • The radionuclides being shipped;

  • The frequency of shipment;

  • The duration of storage and transport;

  • The tasks performed by the individual that involve radiation exposure.

Estimating exposures from the transport of radioactive material using analysis by computer code I–5. The information presented in Section 5, for example in Table 2, may give some initial guidance on this evaluation.
Example 1 I–6. A company will transport approximately three category III‑YELLOW packages per week with an average TI of 3 per package. The weekly number of packages transported may vary, but the annual volume of shipment is expected to be about 150 packages. In this company, the tasks of the driver and the package handler who loads the vehicle are separate.
Example 1 Exposure of the package handler
Example 1 I–7. Footnote b to Table 2, indicates that annual doses below 1 mSv may be expected if six packages each with a TI of 10 are handled annually. For packages with a TI of 3, an annual dose of about 1 mSv would correspond to an annual number of about 20 packages if the same handling scenario as specified in the third column of Table 2 is assumed. In this example, the expected number of packages to be shipped is more than seven times that amount (150 packages), and therefore dose assessment by individual monitoring will be conducted for the package handler.
Example 1 Exposure of the driver
Example 1 I–8. The driver is expected to make one 4 hour journey each week to take the three packages to the consignee, giving an annual driving time of about 200 hours. The packages will be 3 m from the driver, and there is no significant shielding in the truck. The dose rate at the driver’s position from three packages each with a TI of 3, with the application of the inverse square law for a distance of 3 m, is therefore approximately:
Example 2 I–9. A driver will transport an industrial gauge to the company’s sites for use by technicians at those sites. All loading and unloading operations are performed by technicians. The annual driving time is expected to be about 200 hours. The gauge is carried within a category II‑YELLOW package with a TI of 0.1 and is located in the vehicle 2 m from the driver. The dose rate at the driver’s position from one package with a TI of 0.1, with the application of the inverse square law for a distance of 2 m, is approximately:
Example 2 I–10. The driver’s annual dose is therefore expected to be about 0.05 mSv, and no dose assessment programme will be necessary. However, individual monitoring will be conducted for a limited period to confirm this assessment.
Example 3 I–11. Packages are stored in a storeroom with 40 cm thick concrete walls that is 10 m from the office. The packages are stored for a maximum of 1 hour per day, and the maximum cumulative TI in the storage area is limited to 10. With these limits placed on the storage of packages and without considering the effect of shielding by the walls, the dose rate at 10 m would be 1 μSv/h, giving an annual dose of 0.25 mSv. However, the concrete storeroom walls, which are 40 cm thick, provide a dose rate reduction factor of over 100, and therefore annual doses are anticipated to be negligible. Furthermore, the office walls provide some extra shielding, and the average TI of the packages stored will not normally be at the maximum; this will therefore be an upper estimate of the doses received by the office workers.
Optimization of radiation protection I–12. In some transport organizations, a full optimization study may be appropriate. For small to medium sized transport organizations, there may be a number of ways to optimize exposures, and depending on the work circumstances, practical measures can be specified in the RPP; for example:
Optimization of radiation protection I–13. This section may include, for example:
Optimization of radiation protection I–14. Other conditions may be specified, depending on the organization’s procedures, for example with one of the following examples, or a combination of them:
Optimization of radiation protection I–15. The need for package segregation and other protective measures will depend on the dose rates or the TI of the package and the type of operations performed. If category II‑YELLOW or III‑YELLOW packages are stored or loaded on a conveyance, or if the consignment is under exclusive use, specific or special procedures for storage, loading, unloading and tie‑down could be used. These instructions or procedures would be issued under the responsibility of a qualified person.
Optimization of radiation protection I–16. For example, in the case of a single radiography container or gauge, the following might be used:
Optimization of radiation protection I–17. Package segregation is usually needed for operations involving the transport and storage in transit of large numbers of packages containing medical radioisotopes, especially 99Mo/99mTc or 81Rb/81mKr generators or 131I.
Optimization of radiation protection I–18. A number of factors need to be taken into account in determining the segregation of packages from occupied working areas, and it may be necessary to consult a qualified expert in radiation protection. As an example, the RPP could set out the arrangements for storage in transit as follows:
Optimization of radiation protection I–19. Another situation in which segregation from package handling operations is appropriate is the receipt and dispatch of medical radioisotopes at an air cargo shed; for example, a consignment of packages containing medical radioisotopes is received at a cargo shed from a large consignor on four working days each week. The packages are unloaded from the truck in an area of the shed well away from the nearest area normally occupied by other workers. The packages are sorted and placed on pallets in accordance with their respective destinations. The prepared pallets are immediately moved into a shielded storeroom from which they are taken out when they are to be loaded onto a cargo aircraft. The cargo handling staff who perform this work are subject to individual monitoring and typically receive annual doses in the range of 2–3 mSv. The sorting procedure takes approximately 15 minutes. At 3 m from the consignment of packages, the dose rate is about 20 μSv/h. Occupancy at that distance for 15 minutes would give a dose of 5 μSv daily and around 1 mSv annually. Although no other persons are normally present in the vicinity, warning signs and a tape barrier would be placed at about this distance to demarcate the limit of the supervised area for the duration of the work.
Optimization of radiation protection I–20. Consideration also has to be given to other methods of dose reduction; for example, for road transport:
Optimization of radiation protection I–21. The following would reduce the dose to the loaders:
Optimization of radiation protection I–22. Although it is not part of a general RPP, if criticality safety is an issue, then segregation in storage and limitation of the criticality safety index on conveyances will need to be considered for the purpose of criticality control.
Optimization of radiation protection I–23. Arrangements for preparedness and response to emergencies are required (see paras 304–305 of the Transport Regulations), and such arrangements include the provision of instructions by the consignor. For accidents involving radioactive material in storage areas or carried by road or rail, the procedures to be followed are often specified in national legislation, and they may vary slightly from State to State. Similarly, for accidents involving packages being handled at air cargo centres, procedures may be specified in national legislation. These procedures will need to be reflected in the RPP.
Optimization of radiation protection I–24. An example of emergency response procedures for road transport is given below:
  • Implement life saving measures and administer first aid;

  • Assess the risk of, or occurrence of, fire and use the fire extinguisher if appropriate;

  • Contact first responders (e.g. firefighting service, emergency medical service, response forces) as appropriate;

  • Contact a qualified expert in radiation protection and request advice;

  • Inform the “responsible person” at the main (carrier’s) office;

  • Maintain the ability to communicate electronically via telephone, radio and/or Internet.

Optimization of radiation protection I–25. Following notification of an emergency to the main office (see point (e) in the example in para. I–24), appropriate actions will be taken by the office, for example as follows:
Optimization of radiation protection I–26. Subsequent procedures for recovery and cleanup may be included, but these procedures will vary from State to State. An example is as follows:
Optimization of radiation protection I–27. In practice, more specific details would normally be included, for example details of names, 24 hour telephone numbers and exact procedures for dealing with decontamination and waste disposal. Similar procedures can be specified for storage areas and for other modes of transport. More guidance on and examples of such specific emergency response actions and procedures are provided in IAEA Safety Standards Series No. SSG‑65, Preparedness and Response for a Nuclear or Radiological Emergency Involving the Transport of Radioactive Material [I–2].
Optimization of radiation protection I–28. The training of the relevant workers needs to be specified, and a graded approach is necessary to cover the range of tasks involved. Normally, there will be tasks at a managerial or supervisory level (responsible officers) and other training for workers carrying out particular tasks; for example:
Optimization of radiation protection I–29. An example of a consignor’s RPP may include:
  • Completion of transport documents;

  • Preparation of packages;

  • Measurement of dose rates and contamination, and determination of the transport index;

  • Completion and application of package labels;

  • Loading of packages onto the vehicle;

  • [Further tasks as appropriate].’

Optimization of radiation protection I–30. The RPP and associated procedures are part of the transport organization’s management system and are subject to management system processes, such as those for document and version control, document review, issuance and review of instructions and procedures, and follow‑up of non‑conformances. The RPP will be approved by a suitable person within the transport organization, and, if required by national legislation, by the competent authority. Thus, this section of the RPP could state, for example:

The study (document No. RRR) showed that the maximum radiation dose a member of the dispatch staff would receive would be about 3 mSv in a year at the present workload, while the estimated annual dose for a driver was 2 mSv. Workplace monitoring and individual monitoring will be conducted as determined by the qualified expert. Dose records will be maintained.
Optimization of radiation protection II–7. The dose rate monitors and surface contamination monitors recommended by the qualified expert have been procured and are available to ABC Radiopharmaceuticals for regular use. These monitors are calibrated as recommended by the qualified expert. Packages, conveyances and the workplace are monitored by [Name of individual] to verify the continued validity of the results of the initial evaluation.
Optimization of radiation protection II–8. Occupational exposures are kept as low as reasonably achievable by the following means:
  • Increasing the segregation distances beyond the minimum requirements, where possible;

  • Minimizing the presence of workers within 5 m of packages, and implementing job rotation among dispatch workers where there is the potential for high levels of radiation exposure and no other practicable means for controlling exposure is available;

  • Keeping the packages in the shielded bays in the storeroom until as late as possible before loading;

  • Using a trolley to take the packages from the storeroom to the loading area.

Optimization of radiation protection II–9. The radioactive material to be transported is not special form and is carried in appropriate packages in good condition. If damage to packages is suspected, checks for surface contamination will be made by [Name of individual] by taking swabs of the package surface and surrounding areas and by using the contamination monitors available to ABC Radiopharmaceuticals, as appropriate. Periodic (frequency based on a graded approach) checks for contamination are made of the work area and in the delivery vans.

Optimization of radiation protection VI–1. This radiation protection programme (RPP) covers the transport and storage in transit of packages containing uranium oxide concentrate and packages containing sealed sources of 60Co used in industrial irradiators. Vessel X transports consignments of uranium oxide concentrate and special form radioactive material containing 60Co used in industrial irradiators.
Optimization of radiation protection VI–2. Uranium oxide concentrate: Annually, 12 consignments, each consisting of 960 steel drums that are loaded into twenty 20‑foot freight containers, are transported. The steel drums are Type IP‑1 industrial packages. The uranium ore concentrate is classified as low specific activity material (LSA material) in the group LSA‑I. Each 20‑foot container that has been loaded with 48 steel drums has the following dose rates: 0.06 mSv/h at contact and 0.02 mSv/h at 1 m. Each 20‑foot freight container is labelled with a III‑YELLOW label and has a transport index (TI) of 6.0.
Optimization of radiation protection VI–3. Cobalt‑60 sealed sources: Each year, 12 consignments are transported that consist of two Type B(U) packages containing 60Co sealed sources, which are placed in a 20‑foot shipping container. Each shipping container has the following dose rates: 0.9 mSv/h at contact and 0.03 mSv/h at 1 m. Each 20‑foot freight container is labelled with a III‑YELLOW label and has a TI of 9.0.
Optimization of radiation protection VI–4. The scope of this RPP applies from the loading of the consignment onto Vessel X at the originating port facility to the unloading of the consignment at the destination port facility.
Optimization of radiation protection VI–5. The RPP is managed by [Name of individual], who is a suitably qualified person. [Name of individual] will ensure that all the elements of the RPP are implemented, including:
  • Training of workers and implementation of proper work procedures;

  • Assessment of worker exposures, if necessary, by individual monitoring or workplace monitoring;

  • Emergency procedures.

Optimization of radiation protection VI–6. The role of the vessel’s crew and captain is to:
  • Obtain information on the following:

    1. Actions to be taken in the event of an emergency for each consignment;

    2. Conditions for storage, loading and securing of each consignment.

  • Load shipping containers onto the vessel.

  • Segregate and secure containers.

  • Implement actions to reduce doses to workers.

  • Implement emergency procedures, if appropriate.

  • Actions to be taken in the event of an emergency for each consignment;

  • Conditions for storage, loading and securing of each consignment.

Optimization of radiation protection VI–7. The owners of Vessel X or the maritime shipping line operating Vessel X arranged for a qualified expert in radiation protection, who evaluated the possible levels of individual exposure and determined the monitoring programme. The evaluation was made on the basis of:
  • The number and type of packages transported;

  • The category of packages and the TI;

  • The radionuclides in the packages;

  • The frequency of shipment.

Optimization of radiation protection VI–8. The study (document No. RRR) showed that the maximum radiation dose any individual crew member of Vessel X would receive would be significantly less than 1 mSv in a year at the present workload. The qualified expert advised that a dose assessment programme (using individual monitoring or workplace monitoring) was not necessary.
Optimization of radiation protection VI–9. Occupational exposures are kept as low as reasonably achievable by the following means:
  • Stowing all 20‑foot containers under deck within the vessel hull;

  • Positioning all 20‑foot containers door to door to lessen that chances that the doors will open as a result of some external event that results in a significant impact or force applied to the containers during transit;

  • Minimizing the crew members’ presence in the vicinity of the shipping containers;

  • Increasing segregation distances beyond the minimum requirements, where possible.

Optimization of radiation protection VI–10. Under normal conditions, 20‑foot shipping containers that have been prepared for transport do not have any external contamination above allowed limits. If shipping containers appear to have been damaged as a result of an accident, checks for contamination will be performed by an appropriately qualified individual and appropriate action taken if contamination is detected.
Optimization of radiation protection VI–11. All 20‑foot shipping containers are stowed in accordance with the segregation requirements of the International Maritime Dangerous Goods Code (IMDG Code) [VI–3]. If possible, the 20‑foot shipping containers will be stowed such that the minimum segregation distances are exceeded.
Optimization of radiation protection VI–12. In the event of an incident, the following actions will be taken:
  • For dealing with fires and spills (leaks), implement the recommendations in Emergency Response Procedures for Ships Carrying Dangerous Goods (‘the EmS Guide’) [VI–4];

  • Implement life saving measures and administer first aid;

  • Assess the risk of, or occurrence of, fire and use the fire extinguisher if appropriate;

  • Contact first responders (e.g. firefighting service, emergency medical service, response forces) as appropriate;

  • Contact a qualified expert in radiation protection and request guidance;

  • Maintain the ability to communicate electronically via telephone, radio and/ or Internet;

  • With the help of and under the direction of a qualified expert in radiation protection, clean up the affected area and collect the damaged packages and radioactive material, if any;
