| ENS 53181 | 19 January 2018 06:00:00 | Agreement State | Agreement State Report - Lost Tritium Exit Signs | The following was received from the state of Nebraska via email: On 1/19/18, GL0635 (General License) Crete Cold Storage called NEDHHS (Nebraska Department of Health and Human Services), Office of Radiological Health to inquire about reporting requirements if they could not locate GL (generally licensed) devices. Licensee assumed devices were lost during a renovation. Licensee was given reporting instructions via e-mail. On 1/23/18, NEDHHS Office of Radiological Health was notified via letter by GL0635 that four (4) tritium exit signs were reported lost. All four signs were manufactured by Safety Light Corporation, Model 2040, Serial numbers 252778, 252779, 252781 and 252774. Nominal material content is 11.5 Ci of tritium per sign. Nebraska NMED Report No.: NE180001 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.
