ORAU sets the standard for radiological cleanup with collaborative development of MARSSIM

Because cleanup projects require thorough reporting and documentation, it is equally important that independent verification follows a standardized approach that verifies a site is adequately prepared for release.

ORAU’s reputation for superior quality and service was a critical element in the development of the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM). The manual was created by a multi-agency committee representing the U.S. Department of Defense, the U.S. Department of Energy, the U.S. Environmental Protection Agency, and the U.S. Nuclear Regulatory Commission. 

Published in December 1997, MARSSIM provides detailed guidance for planning, implementing and evaluating environmental and facility radiological surveys to demonstrate compliance with a dose- or risk-based regulation. Because of our vast experience in designing and performing independent verification. our qualified staff of radiological professionals made regular contributions and have demonstrated their commitment to the standardization of site survey procedures.

How can MARSSIM benefit my cleanup project?

MARSSIM provides a single, nationally consistent guide for verifying that radioactively contaminated sites have been cleaned up to standards. Combining this information into one manual has increased efficiency, and has eliminated the confusion that can result from contractors having to work from several different manuals.

How can I learn more about implementing MARSSIM at my cleanup site?

ORAU offers multiple five-day training courses for individuals who will be responsible for the decision-making processes involved in the design and implementation of a MARSSIM-based decontamination and decommissioning survey. Courses are offered in Oak Ridge, Tenn., but can also be arranged to accommodate off-site training requests.
