One of the major changes in the IAEA Transport Regulations (n0 TS-R-1 (ST1, revised)) is the explicit requirement for the establishment and application of a Radiation Protection Programme (RPP) for the transport of radioactive material. The present study is based on a related research project funded by the European Commission (EC) and national agencies of the countries involved. The EC project was carried out jointly by three research organisations from three EU Member States (GRS Germany, NRPB United Kingdom and irsn France). This research served as a basis for the development of an International Atomic Energy Agency TECDOC.
The goals of these projects were to identify examples of RPPs and to provide guidance and explanations to elaborate and assess a RPP. Therefore, the guidance is applicable to carriers, consignors and consignees of radioactive materials and to Competent Authorities. The paper also discusses the allocation of the roles and responsibilities of operators in the establishment and application of the RPP.
RPPs define and document in a systematic and structured way the actions and controls to be applied to provide adequate radiation protection of workers and the public. It should cover all transport circumstances including routine and accident conditions of transport. The paper describes and explains the programme structure and the functional elements it should contain consistent with the radiation exposures resulting from the operations. A graded approach is necessary to ensure proper use of resources. Therefore, each of the following programme elements should be implemented and documented with the appropriate level of detail:
· Assignment of the roles and responsibilities
· Dose assessment (prior radiological evaluation, assessment methods, record keeping, worker classification and monitoring equipment)
· Dose limits, dose constraints, optimisation (feedback)
· Segregation and other protective measures,
· Training and information
· Emergency response arrangements
· Quality assurance programme
It is the role and responsibility of the operator to provide for a RPP. Consignors, carriers and consignees should co-operate in this matter. The Competent Authority may check, for example through periodic inspections, that the RPP is correctly documented and implemented: this paper includes information on an assessment of a RPP.
