Dear Jonathan and Radsafers:

10CFR20.1502 probably applies in most states, even though Title 10 is only
for source, byproduct, and SNM.  If the worker is expected to get less than
ten % of his/her permissible exposure (as stated in 10CFR20.1201(a), 1207,
and 1208), no monitoring is required.  I would be interested to know if this
is NOT the case for x-ray in any states.  While many institutions badge
anyway to protect themselves from future lawsuits, there is no regulatory
requirement to do so.

I would suggest that, at the least, several of the workers expected to get
the most radiation would get badged for a few months to establish the upper
occupational limits reasonably expected.  Then take up the issue with the
institution's risk management people.

Ciao, Carol
