RESRAD: Family of Risk Codes
The RESRAD family of computer codes was developed by EVS to provide a scientifically defensible answer to the question "How clean is clean?" and to provide useful tools for evaluating human health risk at sites contaminated with radioactive residues. The RESRAD methodology was cited in DOE Order 5400.5 for dose assessment and determining guidelines for clean-up of radiologically contaminated sites. The RESRAD codes include (1) RESRAD for soil contaminated with radionuclides; (2) RESRAD-BUILD for buildings contaminated with radionuclides; (3) RESRAD-CHEM for soil contaminated with hazardous chemicals; (4) RESRAD-BASELINE for baseline risk assessment with measured media concentrations of both radionuclides and chemicals; (5) RESRAD-ECORISK for assessment of ecological risk from hazardous chemicals; (6) RESRAD-RECYCLE for recycle and reuse of radiologically contaminated metals and equipment; (7) RESRAD-OFFSITE for off-site receptor radiological dose assessment; and (8) RESRAD-BIOTA for assessment of radiological dose to biota. Four of these seven codes (RESRAD, RESRAD-BUILD, RESRAD-RECYCLE, and RESRAD-OFFSITE) also have uncertainty analysis capabilities that allow the user to input distributions of parameters. RESRAD has been widely used in the United States and abroad and has been approved by many federal and state agencies, including the U.S. Department of Energy and the U.S. Nuclear Regulatory Commission.
