DEMONSTRATION OF A COMPUTER MODEL FOR RESIDUAL RADIOACTIVE MATERIAL GUIDELINES, RESRAD

A computer model was developed to calculate residual radioactive material guidelines for the U.S. Department of Energy (DOE). This model, called RESRAD, can be run on an IBM or IBMcompatible microcomputer. Seven potential exposure pathways from contaminated soil are analyzed, including external radiation exposure and internal radiation exposure from inhalation and food ingestion. The RESRAD code has been applied to several DOE sites to derive soil cleanup guidelines. The experience gained indicates that a comprehensive set of sitespecific hydrogeologic and geochemical input parameters must be used for a realistic pathway analysis. The RESRAD code is a useful tool; it is easy to run and very user-friendly.
