| ENS 49602 | 12 November 2013 06:00:00 | 10 CFR 20.2201(a)(1)(i) | Missing Depleted Uranium-238 Shields | Between October 2012 and May 2013, the two customers located in Ridgeland, SC and Tampa, FL shipped depleted shielded Tc-99m generators back to Mallinckrodt in Missouri using courier service companies. The Ridgeland, SC customer, Palmetto Isotopes, shipped three containers; one on 4/29/13 and two on 5/1/13 using the courier ACI. The Tampa, FL customer, West Coast Nuclear Pharmacy, shipped one container on 10/11/12 using the courier Medical Delivery Services. Mallinckrodt has no record of these shields being returned to their facility. Each container has 3.09 mCi of depleted U-238 as a shield. Mallinckrodt uses between 4000 - 5000 total containers to support their customer's needs. A container is declared missing after performing a complete inventory, contacting their customers to verify the Bill of Laden (BOL) information and contacting the couriers who conduct a search and provide a written response to Mallinckrodt. The typical turn-around time for the above is approximately 100 days. The serial numbers, i.e., DU tracking # on box and safe serial # stamped on shield, of the missing sources are as follows: Palmetto - DU tracking # 2185528, safe s/n 608, DU tracking # 2186644, safe s/n 930, DU tracking # 2189415, safe s/n 4947 West Coast Nuclear Pharmacy - DU tracking # 2178372, safe s/n 2146 The licensee contacted R3 (Lambert). This report is similar to EN #47106. 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.

Activity of each one of the doses as of 0400 hours was 61 millicuries, 73 millicuries, 78 millicuries, and 82 millicuries. The second lot number is 95138 it had one dose with an activity of 62 millicuries (as of 0400 hours) of Tc-99m. 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. |
