The Department received notification from the licensee that a portable gauge was lost/stolen. A technician last saw the gauge on August 28, 2025, at 0130 MST at the technician's residence in Fountain Hills, Arizona. On September 3, 2025, the technician arrived at a jobsite at 1040 MST and realized that the gauge was not in the back of his truck. The gauge is a Troxler model 3411, S/N 17318, containing approximately 8 millicuries of cesium-137 and 40 millicuries of americium-241/beryllium. The Department has requested additional information and continues to investigate the event. The licensee has reported the gauge stolen with the city of Fountain Hills. Arizona Incident Number: 25-017 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.
