THE IMPLEMENTATION OF RADIATION PROTECTION PROGRAMMEREQUIREMENTS IN THE TRANSPORT OF NUCLEAR FUEL CYCLEMATERIALS

摘要

The IAEA requires organisations involved in transport of radioactive material to implement aRadiation Protection Programme (RPP) to control radiation dose exposure to both workers and thepublic from transport operations. For nuclear fuel cycle materials, radiation protection is dealt withprior to shipment by using a package design to control exposures to workers and the public. Doseassessment and evaluation is a key issue for RPPs. The extent of control measures in the RPP shouldrelate to the magnitude and likelihood of radiation exposure. The World Nuclear Transport Institute(WNTI) therefore made an assessment of the likely doses to workers in the transport chain, for thevarious modes of transport and for the main nuclear materials. Analysis of the data on dose up-takeduring the various modes of transport of nuclear fuel cycle materials indicates that it is very unlikelythat any group of workers, or any member of the public, will receive annual doses in excess of 1mSvand the transport of nuclear fuel cycle materials should therefore fall into the lowest category, forwhich no workplace or individual dose monitoring is required.
