    Abstract

    The U.S. Department of Energy's Hanford Site has devoted considerable attention to improving the operation of and confidence in the commercially available metal detectors installed at the site. A set of testing and calibration specifications was prepared and applied that yielded appreciable improvements.

    These specifications were based on a set of tests developed to measure portal zone sensitivity and to derive the probability of detection and nuisance alarm statistics. A pragmatic approach to test article selection was also developed. This paper desribes these specifications, their underlying philosophy and methodology, and the results of their application.

    Keywords:

    portal metal detectors, functional tests, sensitivity detection tests, sensitivity verification tests, even false alarm rate tests, sensitivity topography, detection sensitivity topography maps
