Comparison of multimedia model prediction for a contaminant plume migration scenario

摘要

Predictions of four risk assessment models - RESRAD, PRESTO, MMSOILS, and MEPAS - for a test scenario involving the migration of a single, rapidly transforming radionuclide, 90~Sr, and a persistent, long radionuclide chain, 234~U and its progeny, in groundwater are compared. All four models make comparable predictions for the plume centerline concentrations of the primary contaminants in the aquifer for a distance of up to about 300 m from the source.
