=================================================================
The IAEA Basic Safety Standards, Safety Series 115 has the following
interpretation, page 93 II-9 - Dose limitation for comforters and visitor of
patients

..... the dose of any such conforter or visitor shall be constrained so that
it is unlikely that his or her dose will exceed 5 mSv during the period of a
patient's diagnostic examination or treatment. The dose to children visiting
patients who have ingested radioactive materials should be similarly
constrained to less than 1 mSv
