The following information was received from the Commonwealth of
Kentucky by email:
On 11/6/2018, a former licensee [formerly licensed as Wickliffe Paper Co.] reported discovery of a nuclear gauging device (TN [Texas Nuclear] model 5036 originally containing 200 mCi assayed 12/94) that it was unaware it possessed. The license was terminated on August 9, 2016 and at that time, the former licensee provided information related to the disposition of all devices the licensee was aware it possessed. License termination was due to plant closure. During engineering surveys to assess plant conditions for restart, personnel discovered the device still mounted on plant equipment. The former licensee is taking steps to have the device transferred to a licensed manufacturer for disposal. There is no reason to believe any individuals received any exposure at levels which would exceed the regulatory limits."
Kentucky Event: KY180004
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.
