| ENS 55829 | 7 April 2022 04:00:00 | Agreement State | Lost/Missing Gauge | The following was received from the State of Georgia, via email: Graphic Packaging International called us this afternoon to report a missing gauge. The gauge is a Berthold Model LB7441 S/N 2212 and is believed to be about 41 milliCuries. It is unknown to us at this time if the source is Cobalt-60 or Cesium-137. The last leak test was conducted on December 13, 2021. The licensee says that the gauge was installed on a part of the line that they haven't used in a long time. The Radioactivity Safety Officer (RSO) went to that part of the line to clean the tags and discovered that entire end of the line was gone. They have been having demolition work done, so it is his belief that the gauge was in the demolition. The demolition company is Grey Wolf. We are following up with the licensee and the company for more information and will keep you informed. Georgia item number: 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.
