|AGREEMENT STATE REPORT - LOST TRITIUM EXIT SIGN
This is a summary of information received from the state of Nebraska via a phone call:
On November 20, 2019, the state of Nebraska identified a lost tritium exit sign during their quarterly reports. The general licensee indicated that they improperly disposed of the exit sign by donating it to a second-hand store on May 15, 2019. The exit sign has not been located at this time. The second-hand store turns over their inventory every six months, so it is believed that the exit sign has been sold or disposed of.
The tritium exit sign is a Betalux model BX-20-BK (S/N: C167432) with an activity of 17.51 Ci.
No further investigation is planned at this time and Nebraska has closed the event.
Nebraska incident number: NE190005
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.
