| Title | Missing Material Identified During Annual Inventory |
| Event Description | A 5.862 mCi sample of C-14 in a dipropylene glycol propyl ether mix was identified as missing on 2/26/10 during the annual physical inventory of radioactive materials. The sample had been present in its approved storage location during the 2009 physical inventory.
The material was lost sometime between March 2009 and February 2010. The licensee has taken the following actions to locate the material: - Spoke with all authorized users to identify location or usage within the last year; - Detailed search of all storage areas and radioisotope-approved labs; and - Checked waste disposal records. 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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |
