Method for determining radioactive material shipment patterns in urban areas

This report details the development of representative sets of radioactive material shipments into, out of, and through a number of densely populated urban areas. These data represent a large portion of the information required for the assessment of the risks associated with the transportation of radioactive materials in these urban settings. Standard shipment models have been developed for twenty highly populated urban areas, using background data from a 1975 survey of shippers of radioactive materials. These models and the methods and assumptions required for their formulations are presented. Each shipment is specified by the material shipped (nuclide), transport mode, number of shipments per year of that type, size of shipment (curies), transport index (TI), package type, physical form, and material end use (medical/research, industrial, fuel cycle, and waste). 6 refs., 45 tabs.
