| Title | Agreement State Report - Radioactive Material Unaccounted for |
| Event Description | The following was received via email from the Washington Dept. of Health, Office of Radiation Protection:
Tuesday, November 12, 2013, I [State of WA] received a call from the Radiation Safety Officer of the University of Washington. He informed me that his staff was unable to account for 3.3 mCi of C-14 and 7 mCi of H-3, the sum of several vials [unsealed sources used for research], when reconciling the inventory of an AUI [Authorized Investigator] after he died. The AUI had a radioactive materials authorization at the university for well over 20 years. A staff member investigated the problem and interviewed current and previous laboratory staff in an effort to find the documentation of disposition of the missing material. This is believed to be a paperwork/failure to document issue with no actual loss or release. It will be discussed at their next Radiation Safety Committee meeting which the state will attend on 26 November 2013. The licensee will provide us with a full report by then. It is the C-14 which exceeds the reporting activities. State incident number WA-13-056 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.
