Re: Dose Limits to the public
That may be the case. So, how do you ensure that an individual member of
the public is not exposed from some other non-medical source? I don't see
how this can be effectively done, so it seems that you are left with a de
facto limit of 0.25 mSv.
I am sincerely looking for an answer on how to handle this.
