The following is a summary information was provided by the
North Carolina Division of Radiation Protection via email:
On 12/13/2022, the licensee discovered that a source from a shipment of sources received on 9/1/2022, was missing from their inventory. The licensee conducted surveys of the area and did not detect the source. None of the shipping containers or bags were damaged, indicating that the source was not lost during shipping and was either not included in the original shipment from the shipper or was lost after the licensee received the shipment. The original shipper of the source was contacted and informed of the missing source; they are performing checks to verify if the source was indeed shipped to the licensee.

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.
