The morning of Wednesday, October 6, 2021, the Authorized User (AU) discovered that an InstroTek, Inc. model 3500, S/N 3360 (10 mCi Cs-137 and 40 mCi Am-241/Be) portable gauge had been stolen from the back of his work vehicle at his residence. The night before, the AU had secured the gauge with 2 chains and 2 locks to the bed of the truck and the box and trigger were locked as well. The chains had been cut according to the Radiation Safety Officer (RSO). Upon questioning, the RSO assured that gauge storage at personal residences overnight is not an acceptable practice and that the AU has current Department of Transportation training, which has not been verified by Colorado Department of Public Health and Environment. The incident was reported with the Denver Police Department.

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.
