| Title | Missing Two General License Kr-85 Aerosol Neutralizers |
| Event Description | Two TSI Model 3054 Aerosol Neutralizers containing 10 mCi Kr-85 each as of 1977, delivered to the Andrew W. Breidenbach Environmental Research Center (AWBERC or US EPA Cincinnati) facility in Cincinnati, OH can not be accounted for in available US EPA Cincinnati inventory records. The devices were delivered to their facility on 4/21/1977. The device serial numbers are 290T and 291T. The licensee began their investigation after receiving a letter from the U.S. NRC on 8/5/15 which identified that these devices should be in their possession. Members of the US EPA Cincinnati staff completed an exhaustive search of all available records and located radioactive inventories dating back to 1983, but could not locate any records prior to 1983. The 1983 inventory did not list the devices in question. As part of their investigation, the licensee contacted the manufacturer who has no record that the devices were returned. In addition, the US EPA facility in Research Triangle Park was contacted and requested to review their records. That location has no record of ever possessing these devices.
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.
