The following historical information was received from the State of
Tennessee via email:
On March 26, 2013, Kilgore Flares Company and the Division of Radiological Health (DRH) discovered that one of Kilgore's NRD Ionizer devices, model P-2035; S/N A2GK795, was lost. The device contained 40 mCi of Po-210. The device was shipped 10/09/08 from NRD, LLC, located in Grand Island, NY. It was taken out of service in October 2009 when Kilgore renewed the lease for the device. Kilgore was under the impression that the ionizer had been sent back to NRD the previous year. Kilgore did not learn until after the inventory list was sent to DRH February 4, 2013, that NRD had not received them. The device was searched for but could not be located. The boxes that contained the devices sat in the shipping department for some time and this is believed to be where the device came up missing. Kilgore reported that they now keep all devices, being sent back, in the Maintenance Planners office until sealed up for shipping. Kilgore provided a report to DRH on 4/2/13.

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.
