| ENS 42653 | 5 May 2006 07:00:00 | Agreement State | Agreement State Report - Missing Tritium Signs | The State provided the following information via facsimile: The Radiation Safety Office of Fort James Operating Company notified the department on 23 May 2006 that one Generally licensed tritium exit sign was missing. The exit sign was noted missing on 5 May 2006 during a corporate inventory of all radioactive material possessed at the site. The sign's bracket was also missing. There was no evidence the sign was damaged while being removed. The Radiation Safety Officer interviewed numerous workers to try and locate the sign but was unable to determine what happened. Isotope and Activity involved: 11.5 Ci (425.5 MBq) H-3. Tritium Exit Sign, S/N M5099. WA State Report No.WA-06-021 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. |
