MULTIMEDIA MODELING OF ENVIRONMENTAL RESTORATION RISKS AT ROCKY FLATS

Computer-based multimedia models are key analytical tools for assessing potential exposure to environmental contaminants as the U.S. Department of Energy remediates its sites at the nuclear weapons complex. This study applies MEPAS, MMSOILS, and RESRAD to actual release site data from the 903 Pad Source Area within Operating Unit 2 at the Rocky Flats Environmental Technology Site using a common set of assumptions. The analysis compares the similarity of multimedia model output in terms of (1) prediction of transport, (2) determination of an individual’s lifetime exposure, and (3) estimation of risk
