| Title | NON-AGREEMENT State Report - Lost Moisture Density Gauge |
| Event Description | The following information was provided by the licensee via phone:
On May 31, 2024, a moisture density gauge (InstroTek Xplorer, model: 3500, serial number: 5130, 10 mCi Cs-137, 40 mCi Am-241:Be) could not be found when an authorized user went to retrieve it from storage for calibration at their Dexter, MI office. The gauge was last inventoried on November 16, 2023, at the licensees Ann Arbor office location and then relocated in January, 2024, to their Dexter location. The licensee inspected their former Ann Arbor location and verified that the space was empty. The licensees Radiation Safety Officer is currently directing ongoing search efforts. 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.
