Linda, At TVA- Sequoyah we perform entrance passive monitoring using a log. Our GEM-5s are able to see approximately 0.55% of an ALI using our radionuclide mix, based on the sensitivity study we have performed. Individuals who enter an RCA pass through 2 GEM-5s before leaving our site, at the RCA exit, and at the PA exit. We take credit for passive monitoring, and only perform whole body count if an individual alarms a GEM-5, or has known intake incident.

Please use caution when opening. Hi All, I don't see a recent benchmark on this subject. Does your site perform exit whole body counting? If no, do you have any special documentation for passive monitoring or just take credit for the normal RCA egress process? For Diablo Canyon we currently do perform exit whole body counting. Thanks and Happy Thanksgiving, Linda Linda M.
