TYPE A PACKAGE LIMITS OF SPONTANEOUS FISSION RADIONUCLIDES

Limits on the activity allowed in Type A packages in transport are prescribed in the International Atomic Energy Agency (IAEA) “Regulations for the Safe Transport of Radioactive Material,” Safety Standards Series No. TS-R-1 (IAEA 2000a). Type A packages are designed to withstand normal conditions of transport (including minor mishaps) and are intended to provide economical transport for limited-activity packages while achieving an appropriate level of safety. Limits on the content of the packages ensure that the radiological consequences of severely damaged packages are not unacceptable. The numerical value of the content limits are based on the Q-System initially developed by Macdonald and Goldfinch (1980) and further developed by Bologna, Eckerman, and Hughes (IAEA 2000b)
