| Title | Missing Source |
| Event Description | The following information was received from the Wisconsin Department of Health Services (the State) via email:
On March 11, 2024, a contracted service provider was on-site to dispose of 6 sources housed in a Kevex Model 6700 Analyst. It is a 2000 Series Spectrometer, Serial Number A011E, Bench Number 5026. The Analyst [device], has been in the possession of the scrap facility for at least a decade but was never utilized. The device was identified in November 2023, as a device which contained radioactive material. At that point the State was notified, and plans were initiated to dispose of the material. The State was unable to determine who previously possessed the device, or to whom it was initially distributed. The device should have contained 3 Cd-109 pellets of 7 mCi each, and 3 Am-241 pellets of 7 mCi, each. The source serial number indicated on the labeling is 4047, Model 0202. The assay date was December 1, 1992. When the service provider disassembled the device to reach the source housing, no sources were present within the device. The service provider performed confirmatory surveys to ensure that no sources were present. Apparently, the sources were removed prior to the scrap yard receiving the device. Without knowing the provenance of the device, it is unclear whether the sources were ever properly disposed of, therefore, it is being reported as missing material. 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.
