RISK ASSESSMENT WITH INTERTRAN FOR A SUBSET OF TRANSPORTS OF RADIOACTIVE MATERIALS IN THE FEDERAL REPUBLIC OF GERMANY

An important subset of all transports of radioactive materials are those by rail. All transports in one year ( 1983) have been analysed with the aid of the computer code INTERTRAN, supplied by the IAEA to Member States in I 983. The resulting collective radiation exposure to different subgroups of the public and of railway workers has been determined. Work was concentrated on the derivation of well founded input values in order to obtain meaningful results. The values adopted are discussed. Finally the calculated radiation exposure to railway workers is compared with independent estimates of the Federal German railway authorities on the basis of parameters such as SOJOUrn times, exposure distances, etc. The comparison indicates that the results presented should form a reasonable basis for a comparison of health impacts from incident-free transports of radioactive materials and from transports involving accidents.
