Title
Standard Guide for Laboratory Evaluation of Automatic Pedestrian SNM Monitor Performance
ASTM International
Publication Date:
Jun 10, 1997
Scope:
The requirement to search pedestrians for special nuclear material
(SNM) to prevent its theft has
long been a part of both United States Department of Energy and United
States Nuclear Regulatory
Commission rules for the physical protection of SNM. Information on
the application of SNM monitors
to perform such searches is provided in Guide C 1112. This guide
establishes a means to compare the
performance of different SNM pedestrian monitors operating in a
specific laboratory environment.
The goal is to provide relative information on the capability of
monitors to search pedestrians for
small quantities of concealed SNM under characterized conditions. The
outcome of testing assigns a
sensitivity category to a monitor related to its SNM mass-detection
probability; the monitor's
corresponding nuisance-alarm probability for that sensitivity category
is also determined and
reported.
The evaluation uses a practical set of worst-case environmental,
radiation emission, and radiation
response factors so that a monitor's lowest level of performance in a
practical operating
environment for detecting small quantities of SNM is evaluated. As a
result, when that monitor is
moved from laboratory to routine operation, its performance will
likely improve. This worst-case
procedure leads to unclassified evaluation results that understate
rather than overstate the
performance of a properly used SNM monitor in operational use.
The evaluation applies to two types of SNM monitors that are used to
detect small quantities of
SNM. Both are automatic monitors; one monitors pedestrians as they
walk through a portal formed by
the monitor's radiation detectors (walkthrough or portal monitor), and
the other monitors
pedestrians who are stationary for a short period of time while they
are monitored (wait-in
monitor). The latter can be a portal monitor with a delay mechanism to
halt a pedestrian for a few
seconds or it can be an access-control booth or room that contains
radiation detectors to monitor a
pedestrian waiting for clearance to pass.
The values stated in SI units are to be regarded as standard.
This standard does not purport to address the safety concerns, if any,
associated with its use. It
is the responsibility of the user of this standard to establish
appropriate safety and health
practices and determine the applicability of regulatory limitations
prior to use.
