Full Description

1.1 This guide is one of a series on the application and evaluation of special nuclear material (SNM) monitors. Other guides in the series are listed in Section , and the relationship of in-plant performance evaluation to other procedures described in the series is illustrated in . Hand-held SNM monitors are described in of Guide C 1112, and performance criteria illustrating their capabilities can be found in .

1.2 The purpose of this guide to in-plant performance evaluation is to provide a comparatively rapid procedure to verify that a hand-held SNM monitor performs as expected for detecting SNM or alternative test sources or to disclose the need for repair. The procedure can be used as a routine operational evaluation or it can be used to verify performance after a monitor is calibrated.

1.3 In-plant performance evaluations are more comprehensive than daily functional tests. They take place less often, at intervals ranging from weekly to once every three months, and derive their result from multiple trials.

1.4 Note that the performance of both the hand-held monitor and its operator are important for effective monitoring. Operator training is discussed in .

1.5 The values stated in SI units are to be regarded as standard.

This standard does not purport to address all of the safety problems, 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.
