Currently, Tanks Farms Transition Projects require personnel to perform a whole body survey with portable survey instrumentation prior to entering an automated counting system capable of performing a whole body survey. This practice is redundant since automated whole body survey devices are, in most cases, more sensitive and are less likely to be used incorrectly than portable instrumentation. Additionally, Article 221.2 of the Hanford Site Radiological Control Manual (HSRCM-1) states ``Monitoring for contamination should be performed using frisking equipment that under laboratory conditions can detect total contamination of at least the values specified in Table 2-2.`` Based on this criteria implementing the use of an automated whole body survey device would save significant time, money and reduce the current crowding and potential loss of contamination control that now occurs during peak times at step off pads. This document describes implementation process for applying PCM-1B instruments to perform personnel release surveys
