"On November 10, 2023, the licensee determined that an additional four Peco Controls Gamma 101P gauges were missing (serial numbers 0550LX, 9145LV, 9142LV, and 9580LV). Each gauge contained 300 millicuries of Americium-241. Department inspectors were onsite and physically verified the remainder of the licensee's inventory.

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.
