| ENS 55846 | 15 April 2022 05:00:00 | Agreement State | Lost Tritium Exit Signs | The following was received from the state of Nebraska, Office of Radiological Health via email: We (Office of Radiological Health) received Central Valley Agriculture GL0746's Annual Radioactive Material Current Inventory and they indicated that they were no longer in possession of 2 tritium exit signs. We spoke with them and they said that the Oak Street property had been sold several years ago and the building torn down. We contacted the new property tenant to confirm, and it was determined that the signs were not on the property, assumed to have been demolished with the previous building. Follow-up complete, no further investigation is needed. Nebraska event number: NE220001 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.
