| Title | Lost Depleted Uranium Shields |
| Event Description | Mallinckrodt reported the loss of six (6) depleted Uranium shields used as shielding for Tc-99m generators. The licensee believes that the shields were lost in transit between 5/2013 and 9/2013. Five of the shields were in transit between Mallinckrodt and Triad Isotopes (locations in Texas and Hicksville, NY) shipped by "Associated Couriers." One of the shields was in transit between Mallinckrodt and Cardinal Health (Plainville, NY) shipped by "Medical Delivery Services." Each shield is roughly 12 inches in height, 8 inches in diameter, 65 pounds in weight, and contains 8.1 mCi of Uranium. The dose rate on contact would be roughly 3.1 mrem/hr, and the dose at 1 foot would be roughly 1.2 mrem/hr.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
