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!
