| Title | Lost Ionizer Devices |
| Event Description | During a review of records on May 10, 2012, the licensee was unable to account for 4 NRD Nuclecel In Line Ionizer model number P-2021 1000. A thorough sweep of the facilities was completed on May 16, 2012 at 1600 HST. The sweep failed to locate these devices and they were declared lost.
The materiel involved were four devices, each containing 10mCi of Polonium-210 and encased in a steel pressure welded cylindrical case, each approximately 2.3 inches long and .5 inches in diameter. The circumstances under which the loss occurred were that one shipment of 2 devices (Serial Numbers: A2HE600A/A2HE601A) were last known to have been delivered to the licensee logistics center in August 2010 and there were no record of those two items having been returned to NRD, LLC. These two items were received from NRD on 7/8/2010. A second set of two devices (Serial Numbers: A2HT541/A2HT540) were last known to have been in a sealed package in the possession of a Boeing employee in March, 2012. These items were received from NRD on 7/14/2011. All devices are presumed lost and potentially disposed of as ordinary waste. The casing of all devices were known to be intact at the time of loss and no exposure has occurred. A thorough review of shipping records and site wide physical search have been conducted and failed to account for the devices. In the future, all such devices will be subject to the accountability rules, requirements, and procedures established by the USAF Bio-Environment office, Hickam Air Force Base, Honolulu, Hawaii. Internal company procedures will be updated to conform to the requirements of the USAF Bio-Environmental Office, Hickam Air Force Base. 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.
