Abstract:
Estimation of the potential radiological risks associated with highway transport of radioactive

materials (RAM) requires input data describing population densities adjacent to all portions of

the route to be traveled. Previously, aggregated risks for entire multi-state routes were

adequately estimated from population data with low geographic resolution. Current demands for

geographically-specific risk estimates require similar increases in resolution of population

density adjacent to route segments. With the advent of commercial geographic information

systems (GISs) and databases describing highways, U.S. Census Blocks, and other information

that is geographically distributed, it became feasible to determine and tabulate population

characteristics along transportation routes with l-kilometer resolution. This report describes an

automated method of collecting population data adjacent to route segments (for calculation of

incident-free doses) based on a commercial GIS. It also describes a statistical method of

resolving remaining resolution issues, and an adaptation of the automation method to collection

of data on population under a hypothetical plume of contamination resulting from a potential

transportation accident.
