Columbia Generating Stations limits for fixed contamination on hand tools is <5000 ccpm/probe area, <1000 dpm/100cm2. Hand tools exceeding these limits are decontaminated or controlled for use in Contaminated Areas only. SAM used for tools returned to the Tool Crib is set at 35,000 dpm.

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) Eric M.
