The licensee may have also written into their institutional Radiation Safety Manual  and license application specific criteria as to when they were going to use extremity dosimeters (above and beyond when required by regulation).  Those criteria would be enforceable by the regulatory body.

Subject: [ RadSafe ] 10CFR20 question

Hi-I am a student at U of M and am taking a lab that requires I familiarize myself with 10CFR20 (among other things!)

My question is this:

Under what circumstances, if any, is the use of extremity monitoring required under NRC regulations?

I found in 10CFR20.1502 (a) the circumstances that require and individual to monitor for external dose, but can't seem to find anything that deals solely with extremity monitoring.

Any help is appreciated!
