The Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) provides detailed guidance on how to demonstrate that a site is in compliance with a radiation dose- or riskThe probability of injury, disease or death from exposure to a hazard. Radiation risk may refer to all excess cancers caused by radiation exposure (incidence risk) or only excess fatal cancers (mortality risk). Risk may be expressed as a percent, a fraction, or a decimal value. For example, a 1% excess risk of cancer incidence is the same as a 1 in a hundred (1/100) risk or a risk of 0.01.-based regulation. MARSSIM focuses on the demonstration of compliance during the final status survey following scoping, characterization and any necessary remedial actions. Learn more about the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM).
MARSSIM, Revision 1 (August 2000), including the June 2001 updates, is available in electronic format only.
