For D.C. Cook:
1) TLD remains on lanyard with badge (approximately mid-sternum), ED goes into PC pocket 2) N/A 3) The procedural guidance is for the TLD and ED to be within 4 inches, we have not seen significant discrepancies due to this placement. The one instance in which we did see a discrepancy was a discrete particle that was located directly on the ED. In this case we did a SDE calculation and used the TLD as the record DDE dose.

The new TLD has been integrated into the keycard lanyard. For work in CAs we have used an ED/TLD orientation card that fit into the PC pocket. Our new TLDs do not easily integrate into our existing cards. 1) Where do your workers typically place the TLD/DLR and ED when working in PCs? 2) If both are placed in the PC pocket, how do you keep the ED separate from the TLD/DLR? 3) If they are not both placed in the PC pocket, have you had any issues with ED/TLD discrepancies attributed to this possible positioning difference? Please provide a contact for follow-up questions. Thanks!!! Linda Linda M.
