MISSING TRITIUM SIGN
3M Corporation Office located in Saint Paul, Minnesota, was notified this morning from their office located in Brookings, South Dakota, that during a semi annual sealed source inventory it was discovered that a tritium sign containing 20 curies of tritium, as of May 1998, was found to be missing. The on-site Radiation Safety Officer is starting a plant investigation process to determine to try and find the missing tritium sign. The sign was accounted for during their previous semi annual sealed source inventory in July 2006.
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.
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
