| ENS 45041 | 29 April 2009 05:00:00 | Agreement State | Agreement State Report - Missing Tritium Exit Signs | The Nebraska Office of Radiological Health provided the following report via e-mail: The (Kellogg USA) facility was not able to locate four H-3 exit signs (SRB Model BXU20WS containing 17.51 Curies (each) of H-3, for serial #'s 217897, 217965, & SRB Model B100BX20 containing 17.51 Curies (each) of H-3 for serial #'s 220063 and 220071) while completing their annual inventory. They have made a number of searches and can not locate the four missing signs. The company is planning on the removal and proper disposal of all H-3 exit signs in the facility by 8/31/2009. The facility has 230 plus exit signs. Nebraska Report NE090010 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. | ||
| ENS 44343 | 1 May 2008 05:00:00 | Agreement State | Agreement State Report - Lost Tritium Signs | This report was submitted by Nebraska via e-mail: The general licensee, which is a large food processing facility, did its annual inventory in May of 2008. Four Tritium exit signs were discovered missing during the inventory. Sign 1 was in a high traffic forklift area. The sign was protruding from the wall at a right angle. The licensee thinks that it was likely knocked off and disposed of improperly in regular trash. Signs 2 and 3 were colocated in the same holder. They were in an area of construction and maintenance. The licensee can not find them. They may have been disposed of improperly in regular trash but the licensee was unable to determine how they were disposed of. Sign 4 was located in a warehouse overhead area and was likely knocked down via forklift traffic. It was improperly disposed of in regular trash. This general licensee will communicate to all hourly, salaried and outside contractors the importance of maintaining control of the exit signs and notifying appropriate people in the event they become dislodged, or need to be removed or relocated. The licensee will increase inspections on the signs in their current locations in order to verify that signs are still there. The general licensee will begin systematically changing out a set number of the signs each year with nonradioactive materials until all are removed from their facility.

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 |
