The following was received from the State of
Texas (the Agency) via email:
On January 10, 2022, the licensee notified the Agency that on Saturday, January 8, 2022, one of its technicians had taken a Troxler 3440 moisture/density gauge (SN: 37429) to their residence after completing a job and left it secured in the back of his pick-up truck. On the morning of January 9, 2022, the technician discovered the gauge had been stolen from the truck and reported the theft to his supervisor and a report was made to the police. The licensee has notified the local gauge service company, will search the area where the gauge was stolen, and will investigate posting reward poster(s). More information will be provided as it is obtained in accordance with SA-300.
Activity of the sealed sources are not known at this time. Troxler specifications indicate the typical sources to be Cesium-137 (8 mCi) and Americium-241/Be (40mCi) at the time of manufacturing.
Texas Incident Number: I-9907
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.
