| ENS 55952 | 27 May 2022 04:00:00 | Agreement State | Lost Tritium Exit Signs | The following was received from the state of New Jersey, Radioactive Materials Program via email: The Radiation Safety Officer (RSO) of Bristol Myers Squibb notified the NJ Department of Environmental Protection that two H-3 exits signs were unable to be located and cannot be found. The RSO believes that the signs were improperly disposed of during facility renovations as demolition waste. The licensee conducted an in-depth exit sign inventory but was unable to locate the two exit signs. Loss of material was confirmed on 5/27/2022. Equipment: H-3 exit sign, SRBT model BR-20-BK, serial numbers C083389 and C083421, 21.6 Ci per exit sign. State Event Report ID Number: NJ-22-New 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.
