The Radiation Safety Officer of St. Vincent Hospital reported that the facility received a radiopharmaceutical shipment of
I-131 with excess surface contamination on the outside of the shipping container. When the surface of the shipping container was initially swipe tested, the contamination was measured at 734 dpm per 100 sq centimeters. A follow-up swipe survey pinpointed the contamination to just one side of the shipping container and was found to be 581 dpm per 100 sq centimeters. Additional isotopic analysis determined that the radioactive contaminant was
I-131. Integrity of the package was not compromised. The inside of the shipping container was tested and found to be clean. The two
I-131 vials in the container were also verified to be intact and clean. The hospital called the radiopharmaceutical supplier, Cardinal Health Systems of Indianapolis, to notify them of the contamination found on the package. The shipping container has been isolated in a controlled area at St. Vincent Hospital.
