Exposure from a Medical Treatment Source

On July 21, 2017, at a hospital in Seoul, an incident occurred when the assigned staff member failed to follow the patient verification procedure in the I-131 therapy room. As a result, a dose of I-131 (5,550 MBq), intended for a thyroid desease patient, was mistakenly administered to another patient. The misadministrated patient had been hospitalized since July 19 for MIBG therapy and had already received a dose of I-131 (7,400 MBq). Due to the misadministration, the additional thyroid absorbed dose was estimated to be between 15.6 and 24.4 Gy.
