The following report was received from the State of
Texas via email:
On July 26, 2011, the Agency was notified by the licensee that a Humboldt model 5001 EZ moisture/density gauge serial number 3567 was stolen out of one of their trucks in Houston, Texas. The gauge contains a 40 milliCurie Americium-241 source and a 10 milliCurie Cesium-137 source. The gauge was locked in the back of a pickup parked at a training center where the user was attending safety training. When the user returned to the truck, he found the lock and chain securing the gauge had been cut and the transport case with the gauge was missing. The user contacted his employer who then contacted local law enforcement who responded to the scene. The licensee's Radiation Safety Officer also responded to the scene. The licensee believes that the gauge operating trigger was locked, but could not state that with all certainty. Additional information will be provided as it is received.
Texas Incident No.: I-8875
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.
