Hi All, I am not receiving any Powernet postings, but apparently I can post. Sorry for the late reply. 2) Every 24 hours until it's gone unless RP engineering/HP prescribes other recount frequencies. 3) Program is set up so that if certain nuclides are ID'ed on body count it requires immediate contact with RPM or Senior HP. Those people will determine if urine and/or fecal is required and specify protocols. We have done both fecal and urine sampling in the past. One of our units has had some minor issues with fuel integrity...and that is all it takes. 4) Yes 5) Depends on what the sample is for. We do both. We typically do spot urines for H-3 issues. We have done 24 hour urines for non tritium intake evaluations where we wanted to supplement body counting.

V. C. Summer would like to know what kind of in vivo counting protocols your nuclear plant has when you have workers with significant (>10 mrem beta/gamma + alpha) measured internal doses. 2. Do you follow a set counting frequency every time so that the counts can be done by HP Techs without input from a Staff Health Physicist or other qualified technically-qualified individual? 3. If you ever experience significant alpha intakes at your nuclear plant that require you to perform in vitro bioassay (fecal and urine sampling), do you follow a set collection protocol for each sample type that is set up for being run by HP Techs without Staff HP or other technically-qualified individual input? 4. Do you have separate protocols for fecal sampling and urine sampling? 5. If you use urine sampling for in vitro, do you specify 24-hr urine or spot urine?
