Radiation protection principles underlying the IAEA transport regulations and transport experience under normal and accident conditions

The experience obtained over the past 30 years demonstrates that the transport of radioactive materials has achieved a high standard of safety. Under normal conditions of transport, individual doses were shown to be within the dose limits recommended by ICRP. Accident experience indicates that, although accidents have occurred, the resulting radiological consequences were not serious. It is therefore concluded that the transport regulations are, in general, adequate and effective. However, to take into account operating experience, technical advances, and the continual increase in numbers of radioactive material shipments, the transport regulations and their effectiveness are examined from time to time. The next revision is planned for 1983 and work has already begun. The goals of such an examination are to ensure that regulations are technically current in order to limit radiation doses to all exposed individuals to a level as low as reasonably achievable, to avoid any unnecessary exposure, and to further reduce the already small risks of accidents in a cost-effective manner
