Palo Verde provides the following response:
Hand tools in the Radiological Controlled Area (RCA) do not have any removable
contamination on them. Tools stored in the Hot Tool Crib pass a tool monitor
set to 20,000 dpm. Tools in maintenance shops outside the RCA are surveyed as
part of routine contamination surveys. Common hand tools inside the RCA are
stored inside and not released from the RCA.

Subject: Powernet: Limits on contamination for hot tools?
This question has probably been asked and answered before but I'm wondering
what you'all use for acceptable limits for contamination on hot tools (not
those specifically designated for containment). I assume no detectable
smearable (< 1k dpm/100 cm2) but how about fixed? 5k dpm/probe area? Any
specific criteria for what total activity the tool exhibits if placed in a SAM?
Such as 20 nCi (~50k dpm)?
Thanks, Eric (San Onofre HP Tech Support)
