North Anna's response From: [email protected] [mailto:[email protected]] On Behalf Of Benjy P Bertossi Sent: Tuesday, July 16, 2013 6:53 AM To: [email protected] Cc: James P Stewart Subject: Powernet: DLR / TLD practices
Fermi 2 will be installing hand geometry this year and will allow security keycards to go home. We currently store our DLRs on security key cards and would appreciate your input on the below questions: 1) What type of DLR (TLD, OSL, Film) do you use? TLD (Harshaw ICN TLD 760 Badge type 16) 2) Does your site take DLRs home? Yes, We also have a spot at the security entrance where you can store them if you like. 3) If no, how/where do you store them on site? 4) If yes, do you use control dosimetry from on-site, off-site, or both to subtract background radiation? On-site. We performed a study with various employees prior to implementation where we gave them a TLD to store at their home to determine if we had any major background deltas. 5) How do you do DLR exchange and how long does it take you? We change them out semi annually Jan. 1st and July 1st. Usually takes about a week to get 90% of them back and then another week or two to chase down the last 40 or so stragglers. 6) Any other pros/cons of taking DLRs home vs staying on site? Please respond to Powernet or Jim Stewart directly, [email protected]<mailto:[email protected]> (734.586.1388) Thanks, Benjy Benjy Bertossi Fermi2 - RP Supervisor 734-586-4935 [email protected]<mailto:[email protected]> CONFIDENTIALITY NOTICE: This electronic message contains information which may be legally confidential and/or privileged and does not in any case represent a firm ENERGY COMMODITY bid or offer relating thereto which binds the sender without an additional express written confirmation to that effect.
