North Anna's response: 1. No frisking required. Traveling from one RCA to an adjacent RCA.

If background levels do not allow (> 200 cpm) then guidance is provided to the worker for a hands & foot frisk and to proceed to the nearest monitoring station. 4. Previously yes. We now require a whole body frisk prior to exit unless background levels do not allow.
