Title	Lost Source
Event Description	The following summary of events was received via phone call and email from the New Mexico Environment Department, Radiation Control Bureau (the Bureau): The licensee reported a lost source to the Bureau on December 7th, 2023. The source was described as a mixed gamma button source S/N 64820-570, 25.4 mm diameter, 1/8 inch thickness, containing multiple isotopes of low activity. The isotope with the highest present day activity was Am-241 with an activity of 0.253 microcuries. All of the other isotopes had a negligible activity by the Bureau's reporting criteria. The source was shipped by the licensee and considered lost on December 7th after receiving an email from the common carrier that they were not able to locate the shipment. There is no evidence that any individual was potentially overexposed as a result of the lost source. New Mexico Incident #: N/A 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.
