| ENS 46076 | 17 June 2010 05:00:00 | 10 CFR 20.2201(a)(1)(i) | General License Tritium Exit Sign Missing | During a remodel of Wal-Mart Store #566 in Boonville, Indiana, the remodeling contractor found one tritium sign. According to the Wal-Mart Radiation Safety Officer (RSO), the sign was an Isolite model with an estimated 11 Curie source strength. The contractor was instructed to properly isolate and store the tritium sign. When a Wal-Mart consultant arrived at the Wal-Mart store to inspect the tritium sign, the sign could not be found in the storage location. Wal-Mart considers the tritium sign to be lost. 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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source | ||

A Wal-Mart corporate representative reported that Wal-Mart was unable to account for an additional 2439 tritium exit signs (which are general licensed materials) that were used at one time in Wal-Mart stores throughout 14 non-agreement States and the Commonwealth of Puerto Rico. Wal-Mart had previously reported between September 16 and December 1, 2008, to the NRC a total of 29 unaccounted for tritium exit signs in several of the non-agreement states (see also EN #44495). The Wal-Mart representative informed the NRC that they had exhausted their search for the tritium exit signs and considered them to be lost and/or missing. The NRC was provided a listing from Wal-Mart of the store locations along with information on the tritium exit sign manufacturers, model and serial numbers and curie content if known. Notified R1DO (Burritt), R2DO (Blamey), R3DO (Duncan), R4DO (Lantz), FSME EO (Burgess) and ILTAB via email.
