| Event Description | A series 50 nuclear accident dosimeter S/N AP237 with a 1 gram 62 mCi Pu-239 source was determined missing on 10/13/17. The dosimeter was one of 14 received by Idaho State University from the Department of Energy (DOE) in 1991. In 2003, this particular dosimeter was found to have detectable surface contamination and determined to have a compromised source. The device was removed from local inventory in 2003 pending transfer. Attempts were made to transfer the device to Idaho National Lab (INEL), but were declined. The device is believed to have been placed in the Idaho State University nuclear waste stream, and may have been transferred in 2006 or 2011 with other waste via Thomas Gray to US Ecology, but there are no supporting records. Investigation is ongoing.
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.
