| ENS 55998 | 15 July 2022 04:00:00 | Agreement State | Lost Source | The following information was provided by the Pennsylvania Bureau of Radiation Protection via email: On July 15, 2022, the licensee discovered a lost Americium-241 source. The 100 millicurie source is in a FILTEC model FT-50 gauge (Serial Number 116888). During an inventory for its license renewal, the licensee discovered the device missing from its location in storage and has been unable to locate the device. The licensee has notified its facilities and engineering departments, plans on contacting the manufacturer on July 18th to see if the gauge was returned, and is actively searching for the source. The DEP (Department of Environmental Protection) was in contact with the licensee over the weekend for information and will update this event as soon as more information is provided. Pennsylvania event number: PA220023 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.
