**THIS EMAIL IS FROM AN EXTERNAL SENDER OUTSIDE OF THE STPNOC NETWORK. BE CAUTIOUS ABOUT CLICKING LINKS OR OPENING ATTACHMENTS FROM UNKNOWN SOURCES. DO NOT PROVIDE PERSONAL INFORMATION SUCH AS SS#, USER ID/PASSWORD, ETC.** I have a related question to Douglas L Noble's question on " TLD Spike Sample Vendor" 1) I would like to know the users of a contractor dosimeter DLRs who perform blind spikes and if there is a particular frequency (e.g., on all personnel DLRs returned for processing)? STP requires at least 15 blind spikes to be sent semi-annually with the personnel DLRs. We also require blind spikes with neutron exposure to be sent once every two years. 2) What radiation types/ANSI 13.11 categories are used for the spikes and is there a particular delivered dose range tested? Blinds are irradiated to an exposure level of 300-600 mrem beta/gamma. There is no neutron standard range, but the exposure is calculated and documented at the time of the exposure. These values are what we compare as part of our quality checks. 3) Is there a particular number of spikes per range and category? We send 15 beta/gamma blinds semi-annually, and we calculate a representative number of neutron blinds that are sent every two years. 4) INPO 05-008 Rev2 had indicated a processor's requirements, but Rev 3 doesn't indicate these requirement. What guidance or requirement drives the performance of blind spikes at your facility? Most of our DLR requirements are listed in our Quality Control procedure for DLR processing. Those requirements generally match the recommendations of ANI for validating vendor performance.

Difficult dealing with them. Their DOE purchasing processes wants the money before the service for the length of the contract. We started going for an annual contract to minimize the amount of up-front money we give them. I'll buy you 2 Pepsi's if you can find someone else...
