Published in 1997 and revised in 2000, the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) provides guidance for planning, implementing and evaluating radiological surveys to demonstrate compliance with dose- or risk-based regulations.

MARSSIM is a valuable tool, providing a single, nationally consistent guide for verifying that radioactively contaminated sites are cleaned to standards. Combining this information into one manual increases efficiency and eliminates confusion that can result when contractors work from multiple manuals.

MARSSIM is the product of a multi-agency committee representing the U.S. Department of Defense, U.S. Department of Energy, U.S. Environmental Protection Agency and U.S. Nuclear Regulatory Commission.

ORAU and MARSSIM

Due to its vast experience in radiological surveys, ORAU was heavily involved in writing the manual. Additionally, ORAU created the first MARSSIM training course.

Since that first course, ORAU has offered many classes for individuals involved in the decision-making processes related to the design and implementation of a MARSSIM-based survey.

The MARSSIM course is offered several times each year in Oak Ridge, Tenn., but can also be arranged to accommodate off-site training requests.
