[ RadSafe ] Airborne tritium question

[Dixon, John E. (CDC/ONDIEH/NCEH)]

I recommend starting with DOE's tritium primer at:

http://energy.gov/sites/prod/files/2013/09/f2/hdbk1079.pdf

Also, for occupational exposures, dose equivalent can be estimated from air sampling and stay times in areas, but bioassay is preferred and should be performed. I believe DOE still requires some kind of biodosimetry for doses greater than 100 mrem/yr from all sources. Environmental effluents should also be monitored (this requirement should be in the facility's license).

Regards,
John Dixon

Subject: [ RadSafe ] Airborne tritium question

This question came from a client.  Its outside my area so any input would be much appreciated. 

The plant currently performs monthly air samples for particulates and tritium in their nuclear sample room and near the spent fuel pit . It doesn't appear to be in any of the technical guidance documents. (It might be a legacy good practice, but that can't be confirmed either).  Since reactor water and the spent fuel pit have tritium, there is probably some guidance somewhere. So, can anybody lead us to documented requirements for routine sampling for particulates and/or tritium in the working areas of a PWR?

Thanks in advance  - -jmr
