Multi-Agency Radiation Survey and Site Investigation Manual

Training | Download the Manual | COMPASS Software Download


Published in December 1997, The MARSSIM manual provides a single, nationally consistent guide for verifying that radioactively contaminated sites have been cleaned up to standards, rather than each regulatory agency having its own manual and standards. Such increased efficiency eliminates the confusion that could often result from contractors having to work from three or four different manuals.


Eric Abelquist 's involvement in the development of the manual gave him the knowledge necessary for working with another ORISE program to quickly develop a training course in the implementation of MARSSIM. This course is offered through ORISE's Professional Training Programs several times a year. Specific information on the MARSSIM course offered by PTP, its schedule, and how to register can be found on the MARSSIM training page on the PTP Web site.

This course, which has been expanded to five days for 1999 offerings, emphasizes the decision-making processes involved in the design and implementation of a MARSSIM-based decommissioning survey. Topics include an overview of radiological survey types, the data quality objectives process, selection and application of DCGLs, background reference area selection, survey instrument detection sensitivity, area classification, statistical design of surveys, measurement uncertainty, and performing statistical tests. It is expected that the course instructors will include the following advisors to the MARSSIM committee: Eric Abelquist (CHP), James Berger (CHP), and Dr. Carl Gogolak. 

COMPASS facilitates the use of MARSSIM and helps in making informed radiological survey decisions.
MARSSIM Implementation Software

The COMPASS software was designed to facilitate the use of MARSSIM and guide the user into making informed decisions in designing final status radiological surveys. COMPASS also simplifies the application of the statistical tests by performing the statistical calculations and providing prospective power curves that help in determining what level of confidence the user is willing to accept for a particular number of measurements or samples for a survey unit. After performing the final status survey, COMPASS assesses the data for comparison to the release criteria.

Installation Instructions
