The U.S. Department of Energy (DOE), U.S. Department of War (DOW), U.S. Environmental Protection Agency (EPA), and the U.S. Nuclear Regulatory Commission (NRC) are announcing the availability for use of Revision 2 of the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM). MARSSIM provides information on planning, conducting, evaluating, and documenting environmental radiological surveys of surface soils and building surfaces for demonstrating compliance with regulations. The manual has not been updated since 2001; updates prior to 2001 primarily consisted of minor non-technical edits. Revision 2 updates the science, clarifies methods, and implements lessons learned from over 25 years of use. MARSSIM Revision 2 is available from https:/ /www.epa.gov/radiation/multi-agency-radiation-survey-and-site- investigation-manual-marssim.
The agency’s own summary, as published.
