CHARACTERIZING, FOR PACKAGING AND TRANSPORT, LARGE OBJECTS CONTAMINATED BY RADIOACTIVE MATERIAL HAVING AN UNLIMITED A2 VALUE

The International Atomic Energy Agency (IAEA) Regulations for the safe packaging and transportation of radioactive materials follow a graded approach to the requirements for both packaging and controls during transport . The concept is that, the lower the risk posed to the people and the environment by the contents, (a) the less demanding are the packaging requirements and (b) the smaller in number are the controls imposed on the transport of the material . There are likely to be a great number of situations arising in coming years when large objects , contaminated with radioactive material having unlimited Az values will result from various decommissioning and decontamination (D&D) activities and will then require shipment from the D&D site to a disposal site . Such situations may arise relatively frequently during the cleanup of operations involving mining, milling, feedstock, and uranium enrichment processing facilities.
