RESRAD, a computer model for deriving residual radioactive material guidelines

The U.S. Department of Energy has established radiological protection guidelines for the cleanup of residual radioactive material at sites administered under its Formerly Utilized Sites Remedial Action Program (FUSRAP) and Surplus Facilities Management Program. The guidelines establish radionuclide concentrations or radioactivity levels that are acceptable if the site is to be used without radiological restrictions. Guidelines can be categorized as either generic (or site-independent), i.e., taken from existing radiation protection standards, or site-specific, i.e., derived from basic dose limits using site-specific models and data. Procedures to derive site-specific guidelines including determination of exposure pathways calculation of pathway factors, and calculations of guidelines are discussed. Use of resrad is also discussed
