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
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.
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.
