PREDICTIVE MODELING OF TERRESTRIAL RADIATION EXPOSURE FROM GEOLOGIC MATERIALS
Models have been developed in two study areas in Southern Nevada that include the alluvium on the western shore of Lake Mohave, and Government Wash north of Lake Mead; both of these areas are arid with little soil moisture and vegetation. In general, we determined that by using geologic units to define the geospatial areas of exposed bedrock and ASTER visualizations to break up and define the geospatial areas of alluvium and colluvium, regions of homogenous geochemistry can be defined allowing for the exposure rate to be predicted for each region.
