Gretchen, let me also add that NVLAP Testing for Extremities is governed by
HPS/ANSI N13.32-2008, Performance Testing of Extremity Dosimeters. 10CFR20.
However, Extremity Dosimeters are not required to be tested by NVLAP per:
§ 20.1501 General.
(d) All personnel dosimeters (except for direct and indirect reading pocket
ionization chambers and those dosimeters used to measure the dose to the
extremities) that require processing to determine the radiation dose and
that are used by licensees to comply with § 20.1201, with other applicable
provisions of this chapter, or with conditions specified in a license must
be processed and evaluated by a dosimetry processor--

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!
