Abstract
WORK with radioactive substances in universities and hospitals is subject to codes of practice1,2 which require the “designation” of a person unless it is most unlikely that they will receive more than three-tenths of the annual maximum permissible dose. This criterion is easier to apply to persons exposed to external radiation only than to those using unsealed radioactive substances where there is the additional requirement of adequate precautions against contamination. I shall set out here criteria for designating individuals working with unsealed sources.
