Abstract

The IAEA Regulations for the Safe Transport of Radioactive Material [1] specify a range of package requirements that are dependent upon the activity and properties of the radioactive material being transported. For example, Type A packages can be used for the transport of material with an activity of up to one A1 of special form material and one A2 of other material. The A1 and A2 values are determined for over 350 radionuclides using the Q system in the advisory material [2]. This system models the following pathways in the event of a severe accident: • External photon dose; • External beta dose; • Inhalation dose; • Skin and ingestion dose due to contamination transfer; • Submersion dose.
