We are curious to know if anyone is performing routine
bioassay for anything other than iodine and tritium, and if
not, how do they justify not doing it?  (For example how do
you justify that a  nuc med tech's uptake of technetium,
gallium, thallium, indium etc or a researcher using P-32 etc
is less than the 10% ALI.)

Thanks in advance.

Try using the Hazard Index calculation in NUREG 1400.  I
think you'll find that a worker would have to handle a
considerable amount of activity or be doing some unusual
experiments to justify routine bioassays.
