| Event Description | The following was received from the Colorado Department of Public Health and Environment (the Department) via email:
On February 14, 2024, the radiation safety officer of CTL/Thompson, Inc. reported a stolen InstroTek model 3500 series portable moisture/density gauge (Serial Number 4764). The gauge user reported they loaded the gauge at their Pueblo office and stopped at their residence to retrieve their wallet. Upon returning to their truck, both chains that secured the gauge and transportation case were cut and the gauge and transportation case were stolen. The gauge contained a 10 mCi cesium-137 source (Serial Number BG1770) and a 40 mCi americium-241: beryllium source (K147/22).The licensee was instructed to file a police report. The Department is waiting for additional details regarding the event. CO Event Number: CO240003 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.
