Generally, years of experience.  It is hard to show any exposure with
sub mCi use of P-32 unless they literally spill the stuff on the
ring badge.  Above that level, a careful person won't pick up
anything, but you can easily spot the careless or less-well trained.
We generally used a 1-5 mCi lower limit: 1 mCi for new people, 5 mCi
for experienced people (e.g., no significant exposure over a period of
time).
