| Title | Missing Nickel-63 Licensed Radioactive Material |
| Event Description | On February 18, 2009, during a scheduled radioactive material inventory activity, a personnel explosive detection device containing 15 mCi of Nickel-63 was discovered missing. A search of the facility has not located the licensed material at this time.
This is being reported under 10 CFR 20.2201 (a)(ii), Loss of licensed material greater than 10 times the quantity specified in Appendix C to 20.1001 - 20.2401 {20.2201(a)}. The personnel explosive detection model information is: Smiths Detection; Ionscan Sentinel II; Instrument Serial Number - 213028; Sealed Source Serial Number (from the manufacturer) - MY 636. The Licensee suspects that this material was disposed as trash. The NRC Resident Inspector has been notified.
Licensee is adding a sentence to the first paragraph "The location of the source remains indeterminate at this time." The licensee is deleting the sentence in the fourth paragraph "The licensee suspects that this material was disposed as trash. The licensee has notified the NRC Resident Inspector. Notified R2DO (Steven Vias). Notified NRR EO (Ross-Lee) and FSME EO (McIntosh) via email. 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. 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 |
