Title: New population and agricultural database construction for the Computerized Radiological Risk Investigation System

Abstract

Oak Ridge National Laboratory has developed a comprehensive dose/risk assessment methodology, the Computerized Radiological Risk Investigation System (CRRIS), for assessment of atmospheric radionuclide releases. Radiological effects are calculated for direct atmospheric and ground exposure and for consumption of contaminated agricultural products. Previously, population and agricultural data for CRRIS were tabulated on 1/2-degree square grid cells. This coarse resolution resulted in anomalies such as population in water bodies, agricultural production in city centers, and nonconservation of population over the assessment grid. An even finer mesh (2-minute square grid) is inadequate in densely populated cities where 20,000 or more people live in a square block. These difficulties ar overcome by a variable resolution technique using US Census Bureau population data at the most detailed level available (enumeration districts in cities or block groups in rural areas) and by excluding population from unpopulated areas (e.g., large water bodies). Agricultural data are available at only the county level and are apportioned to the assessment grid according to farm population. This paper discusses the population database construction using Tennessee as an illustration. 12 refs., 3 figs.
