Tom, the NRC has no regulations with release criteria. Unconditional release requires a determination of "no detectable". I believe some materials licensees have license conditions with specified minimum detection limits such as the old 1k smearable, 5k total. For Part 50 licensees (commercial reactors), see Info Circular 81-07 for surface contamination guidance and Info Notice 85-92 for quantities. Volumetric releases require gamma spec to environmental levels with LLDs specified in the ODCM. If ANSI/HPS N13.12 were ever adopted . . . . Regards, Eric Goldin, CHP

But I still can’t find that meeting on the HPS Online Listing. I have contacted the right people to get the meeting listed. Show up at the HPS meeting on July 10th and I guarantee there will be a discussion about the new “Instrumentation Section” of the HPS. Perhaps in a hallway which is where I get my best information here at Los Alamos National Laboratory. Thanks to David for catching my error.

I hope there is a good response to the instrumentation Section initiative. Thanks for organizing the Power Reactor Section Meeting on Wednesday.

STOP. THINK before you CLICK links or OPEN attachments. Everyone In the DOE we use surface contamination guidelines in 10CFR835 Appendix D, much earlier than 10CFR835 we used Table 1 of DOE Order 5400.5. Our Radiation Protection Program document pretty much incorporates the values in 10CFR835 Appendix D. Each DOE facility is required to have a Radiation Protection Program document but there are differences from one DOE facility to another. Is there a comparable NRC document stating surface contamination guidelines ? What is the impact of “HRA Consultation No. 26-MF-755-00D” ? Is that a useable NRC facility guide ? What do the Canadian members of Powernet use for surface contamination guidelines ? The Power Reactor Section of the HPS will meet on Wednesday July 12 from 08:30 to 10:30 AM at the annual HPS meeting in Raleigh. I would like to discuss this topic and many more at that meeting. I am also trying to arrange a short Monday night (July 11) meeting of those who are interesting in participating in the new “Instrumentation Section” of the HPS. Best regards Tom James (Tom) Voss
