Event Description	A 0.78 Curie (today's activity) Ir-192 source was lost during shipment from the Mayo Clinic in Rochester, MN to Alpha-Omega Services in Vinton, LA. The last known location was Memphis, TN with the common carrier. Its original shipment date was February 8, 2019. The licensee contacted the common carrier upon suspicion of loss on June 4, 2019. On August 7, 2019, the source had not been located and was deemed lost. 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.
