1. What does your site consider a positive WBC? BFN currently considers a bioassay result (in vitro or diagnostic in vivo) that indicates the presence of licensed material in a quantity greater than minimum detectable activity (MDA) for the counter being used as positive. SAME
1. What level positive WBC does your site document a condition report (CR)? BFN currently documents a CR anytime we have a positive WBC greater than the MDA for the counter being used. SAME 1. What information do you record for level 1 PCE due to human performance issues? BFN currently documents a CR and documents survey results on NISP-RP-06 Attachment 4 Personnel Contamination Event Log We only use the log for Level 1 PCEs. BUT we do continue to have outage goals related to level 1 PCEs. 1. What is your sites threshold for a PCE requiring skin dose calculations?

I have included what BFN is currently practicing. 1. What does your site consider a positive WBC? BFN currently considers a bioassay result (in vitro or diagnostic in vivo) that indicates the presence of licensed material in a quantity greater than minimum detectable activity (MDA) for the counter being used as positive. 1.

BFN currently performs a dose calculation if the SDE or LDE dose is likely to exceed 100 mrem (or 10 mrem for DDE) which corresponds to the following values: [cid:[email protected]] James W.
