> In the annals of the USNRC there are at least two cases of nursing mothers who were administered I-131 and subsequently nursed their infants. One case was a diagnostic study and relatively little damage was done to the infant thyroid. The second, at Tripler Army Medical Center in Honolulu, the patient was given a therapeutic dose. The infant’s thyroid was ablated.
> During a routine NRC inspection of a Pittsburgh hospital the staff informed the inspector that a male patient, who had been given 200 mCi of I-131 orally, had had sexual intercourse with a female visitor the day after the administration. The patient was a physician and, according to the staff, the action was not out of character for him,. The hospital tried to get the woman to come in for a bioassay (thyroid count) but she refused. The incident had occurred a year or two before the inspection so no action was taken by the NRC and I don’t believe the incident was documented.
> I don’t know if this is the sort of cross-contamination you are looking for but since all body fluids and the breath contain I-131 after an administration there must be other instances of transfers similar to these.
