The radioactive wig in iodine-131 whole body imaging

A significant amount of I-131 contamination was found in the hair of a Bedouin lady scanned seven days after the administration of an ablative dose of 50 mCi of I-131. This observation should be taken in consideration to avoid false interpretation. It also raises the problem of potentially contaminating other persons coming in contact with I-131 patients after discharge as result of accidental contact or neglecting precautionary measures.
