Re: I-131 procedure bioassay requirement

[Richard Smart <R.Smart@unsw.edu.au>]

Dear Radsafers,

The discussions on the need for bioassays when using I-131 capsules has been
restricted purely to the legal requirements under the various US legislation.

No one has mentioned whether they have ever detected a significant internal
contamination problem from the administration of I-131 capsules, from their
routine bioassays.

Bioassays after I-131 administration are not legally required in NSW,
Australia, and are not routinely performed. Does any one have data which
would suggest that we should be doing bioassays routinely?

Regards
