The following was received from the Commonwealth of
Virginia via email:
Honeywell International is authorized by general licenses to possess a number of tritium exit signs. It was discovered during an internal physical inventory that eight tritium signs were unaccounted. All were distributed by Safety Shield, Inc., and included one Model L3, s/n T8543, 11.5 curies; one Model XT, s/n S1075, 7.5 curies; and six Model 2040's, s/n 207011 through 207016, 7.5 curies each. The signs were received several years ago. Honeywell was unable to locate the signs despite a search of the facility and additional record review. Honeywell has submitted a procedural change in an effort to better track the remaining tritium signs at the facility. The licensee will keep the agency informed of any additional information.
Event Report ID No.: VA-16-002
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.
