Title	NON-AGREEMENT State - Lost Co-57 Marker Source
Event Description	The following is a summary of a phone call with Lester E. Cox Medical Center: On November 23, 2021, the licensee was performing a radiography procedure on a patient's lymph node. The procedure involved the use of a Co-57 marker rod source, approximately 13.1 microCi. During the procedure the shielding cap was removed, reference mark was made, the cap was replaced, and the rod was placed back onto a medical cart. At some point following the procedure the licensee recognized that the source was missing. A search of the lab, linen area, and trash was conducted and did not identify the missing source. 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.
