Fort Calhoun would appreciate your input about TLDs. If you have any procedures that address these items and would not mind sharing, you can email them to [email protected]<mailto:[email protected]>
1. Does your site use some type of a jig to standardize the position of a worker's EAD and TLD or do you just provide guidance to the worker to keep the EAD and TLD together (such as within a hands width of each other and on the front of the body between the waist and head) 2. If you use a jig, did/does its use improve how your TLD vs EAD results match up. 3. If you move dosimetry from the chest location to another location such as the head or Thigh when they are the highest exposed body part, do you record that movement somewhere (survey map, log, etc.)? 4. What is your TLD wear period and minimum reporting level for the TLD? (example, 6 month wear period, 5 mrem reporting level) 5. Is the INPO and ANI criteria the only criteria you use for determining when to investigate TLD vs. EAD results or do you have additional criteria you apply? What is the additional criteria you use? (INPO and ANI criteria - investigate if either TLD or EAD is greater than 100 mrem and > 25% difference between readings) Thanks, Dohn Dohn Little Radiation Health Specialist - Dosimetry [email protected] - (402) 533-7162 Admin Building FC 2-1 OPPD - Fort Calhoun Station 9610 Power Lane Blair, Ne. 68008 [Description: cid:[email protected]] ---------------------------------------------------------------------- This e-mail contains Omaha Public Power District's confidential and proprietary information and is for use only by the intended recipient.
