Portal Metal Detectors at the U.S. Department of Energy Hanford Site


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.
