Dear Jeanne,

I don't deal with P-32, but thought our badging criteria might be of 
interest to you.  I probably tend to overbadge, because I have this 
paranoid fear of having to testify at a "radiation liability" trial 20 
years from now with no badging data for the plaintiff who has been 
working with or near radioactive materials.  So while I'm not 
responding directly to your question, I think I may raise some points 
you may want to consider.

Our badging criteria are:

1)  Individual will receive or is likely to receive an annual external 
whole body dose greater than 100 mrem; or,
2)  Individual will receive or is likely to receive an annual dose to 
the extremities, lens of the eye or skin greater than 10 percent of 
corresponding limits; or,
3)  Individual operates, sets up shots for, or performs maintenance on 
energized radiation producing equipment; or,
4)  Individual will enter posted Radiation Areas or High Radiation 
Areas; or,
5)  Individual could be in proximity to radiation producing equipment 
or radioactive materials under such conditions that a significant 
exposure could occur in an off-normal situation.

I also have an unwritten rule that I will badge individuals who appear 
to be extremely nervous about whether or not they are working around 
radiation in order to demonstrate that they are not being exposed.  I 
find the $ 10.00 badge has tremendous paybacks in program credibility 
with workers, especially non-radiological workers ("I have nothing to 
hide.  Here's a badge; let's see if you get anything.").

Hope this helps.
