Title	Moisture Density Gauge Stolen and Recovered
Event Description	A Troxler Electronic Laboratories, Inc. Model 3430, portable gauging device [serial number 22936, containing approximately 8.0 millicuries of cesium-137, and approximately 40 millicuries of americium-241/beryllium] was stolen from the licensee's vehicle while parked at the Home Depot in Lindon, Utah. The Cs-137 source was in the safe shielded position when it was stolen and the transportation case was also secured. The device had been secured by two independent physical barriers, but both barriers were breached. The device was recovered at approximately 5:55 p.m. MST by licensee personnel. The transportation case had been opened, but the source rod was still secured in the shielded position. The licensee's vehicle was an open bed pickup truck with a mechanism to secure the device as required. Utah Report: UT110001 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.
