| ENS 52941 | 18 August 2017 18:00:00 | 10 CFR 20.2201(a)(1)(i) | Stolen Then Improperly Disposed of Tritium Exit Signs | A trustee prisoner was found to have removed 10 tritium 'bulbs' from 10 tritium exit signs at Marquette Branch Prison. The trustee prisoner was using the tritium bulbs as night lights. Eight of the 10 tritium bulbs were recovered. The trustee prisoner admitted to having broken two of the tritium bulbs and then flushed them down a toilet. The activity level of the tritium bulbs is unknown at this time. The recovered eight tritium bulbs are currently in secure storage. These tritium bulbs will be disposed of by an approved/licensed contractor. The trustee prisoner has been removed from trustee status. 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.
