Abstract

The Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) provides information on planning, conducting, evaluating, and documenting building surface and surface soil radiological surveys for demonstrating compliance with requirements, often as part of a dose- or risk-based regulation or standard.¹ MARSSIM is a multiagency consensus document that was developed collaboratively by four Federal agencies having authority and control over radioactive materials: U.S. Department of Defense (DoD), U.S. Department of Energy (DOE), U.S. Environmental Protection Agency (EPA), and U.S. Nuclear Regulatory Commission (NRC). MARSSIM’s objective is to describe a consistent approach for planning, performing, and assessing building surface and surface soil radiological surveys to meet established criteria, while concurrently encouraging an effective use of resources.

 

¹MARSSIM uses the word “should” as a recommendation, not as a requirement. Each recommendation in this manual is not intended to be taken literally and applied at every site. MARSSIM’s survey planning documentation will address how to apply the process on a site-specific basis.
