The source is approximately 1 year old and the licensee believes the source was disposed of while attached to an air hose which was thrown away." The State is continuing its investigation into this event and will provide updated information when it is available. 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. | General Information or Other | Event Number: 43022 | Rep Org: FLORIDA BUREAU OF RADIATION CONTROL Licensee: BTL ENGINEERING Region: 1 City: TARPIN SPRINGS State: FL County: PINELLAS License #: 1315-1 Agreement: Y Docket: NRC Notified By: STEVE FURNACE HQ OPS Officer: BILL GOTT | Notification Date: 12/04/2006 Notification Time: 14:05 [ET] Event Date: 12/04/2006 Event Time: 11:46 [EST] Last Update Date: 12/04/2006 | Emergency Class: NON EMERGENCY 10 CFR Section: AGREEMENT STATE | Person (Organization): MARVIN SYKES (R1) GREG MORELL (NMSS) MELVYN LEACH (IRD) | Event Text AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE A truck carrying a CPN Model MCI PRT moisture density gauge (10 millicuries Cs-137; 50 millicuries Am-241:Be) was involved in a transportation accident. The moisture density gauge was thrown from the truck when the truck flipped over. The driver was injured and taken to the hospital. The company RSO responded and reported that the gauge remained in its case and the gauge was not damaged. There was no detectable radiation leakage. The gauge is in the possession of the company's RSO who will send it for a leak test tomorrow, 12/05/06. | General Information or Other | Event Number: 43023 | Rep Org: NE DIV OF RADIOACTIVE MATERIALS Licensee: WAL-MART STORE 867 Region: 4 City: SCOTTSBLUFF State: NE County: License #: GL0611 Agreement: Y Docket: NRC Notified By: TRUDY HILL HQ OPS Officer: BILL GOTT | Notification Date: 12/04/2006 Notification Time: 16:59 [ET] Event Date: 04/21/2006 Event Time: [CST] Last Update Date: 12/04/2006 | Emergency Class: NON EMERGENCY 10 CFR Section: AGREEMENT STATE | Person (Organization): LINDA SMITH (R4) SCOTT MOORE (NMSS) EMAIL ILTAB () | This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - MISSING SELF-ILLUMINATING EXIT SIGNS The State provided the following information via facsimile: "Late last winter and early this spring the general licensee hired a consulting firm to do an inventory of the self-illuminating exit signs in Nebraska. They used the inventory lists of exit signs from the Radiation Control Program in Nebraska and lists from the manufacturers of Isolite (Safety Light) and SRB Technologies to make a comprehensive list of exit signs assigned to Nebraska Licensees. This comprehensive list was taken to each store and compared to the signs that were installed. They made more than one trip to the stores to make sure they had an accurate inventory. They discovered that some signs had been returned to the manufacturer and some signs installed in other Wal-Mart stores in and out of Nebraska. The consultants found 2 missing signs at this location. To help with the inventory in the future, the licensee (1) put a sticker on each tritium exit sign with the 'Item Number' assigned by the State of Nebraska, (2) The sign location was marked on a drawing of the store's floor plan, and (3) The inventory information was compiled and stored in a database. The licensee has discontinued having self illuminating signs installed in their stores in Nebraska. They are also considering replacing the signs with non radioactive material exit signs as they remodel stores in the future. They will continue to do inventories of stores in other states and may find some of the missing signs. The consultants discovered that some contractors took signs from one store to another when they had extra signs left after a construction project. The licensee was unable to determine if the missing signs were installed in this location and then removed during previous remodeling or if the signs were never installed at this location."
