EPA’s Office of Air and Radiation (OAR) is working with the Federal Inter-Agency Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) Workgroup on plans to issue a Revision 2 to the MARSSIM . The MARSSIM is the official multi-agency (U.S EPA, U.S. Nuclear Regulatory Commission, U.S. Department of Energy and U.S. Department of Defense) consensus document on planning, coordinating, evaluating and documenting environmental radiological surveys. It provides explicit guidance to federal agencies and other parties, including states, site owners, contractors and private entities on how to demonstrate that their site is in compliance with a radiation dose or risk-based regulation, otherwise known as a release criterion.

The planned update to the MARSSIM is anticipated to include incorporation of an improved treatment of measurement uncertainty, additional survey methods made possible by improvements in technology, more extensive discussion on areas of elevated activity [hotspots and Uranium Mill Tailings Radiation Control Act (UMTRCA) standards], and a variety of other improvements resulting from feedback received from users since issuance of the document. The planned revision reflects changes in science and technology, as well as twelve years of combined Federal experience in utilizing MARSSIM. This effort reflects a major extension of a multi-agency initiative to provide Federal guidance on determining whether a radioactively-contaminated site (including materials and equipment located on or used at the site) has been adequately cleaned up.

To support development of this update, OAR, on behalf of the Federal Inter-Agency MARSSIM Workgroup, has requested an SAB consultation to seek advice early in the process for technical and scientific improvements to MARSSIM leading to the issuance of Revision 2.
