The State of
Maine was notified by a Wal-Mart corporate representative located in Bentonville,
AR, indicating that Wal-Mart was unable to account for 87
tritium exit signs (which are general licensed materials) that were used at one time in Wal-Mart stores throughout the state. The Wal-Mart representative informed the state office that Wal-Mart had exhausted searching for the
tritium exit signs and considered them to be lost and/or missing. The state was provided a listing from corporate Wal-Mart of the store locations along with information on the
tritium exit sign manufacturers, model and serial numbers, and curie content where known.
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.
