| ENS 52720 | 1 May 2017 11:30:00 | The following information was received from the Commonwealth of Kentucky via facsimile: KY RHB (Kentucky Radiation Health Branch) Inspector, Christopher Keffer, was performing a routine health and safety inspection of the licensee when the RSO (Radiation Safety Officer) discovered that a stored device was missing. According to the RSO, the laboratory where the device was stored was cleaned out the week before; it is currently believed that the device has been thrown away and is now in a landfill. The sealed source identification number is NR-536-D-808-B associated with a Perkins Elmer Clarus Model 500. The source is a Ni-63, 15 microCurie source. 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.

| ENS 52265 | 27 September 2016 12:52:00 | The following information was obtained from the Commonwealth of Kentucky via facsimile: KY RHB (Kentucky Department for Public Health & Safety, Radiation Health Branch) was notified on September 27th, 2016 by the Radiation Safety Officer of Gem Engineering, Inc. that a theft of material had occurred sometime during the night of September 26th unto the morning of the 27th. A Troxler 3411 series moisture density gauge that was stored in the back of a vehicle was stolen along with the vehicle. The licensee reported the theft to the police on the morning of the 27th when it was noticed by the authorized user that the vehicle was missing. The device has been recovered by police and returned to the licensee. The individuals responsible have been apprehended as well. The State will continue to keep NRC informed of the status of our investigation. The Troxler contains a nominal 9 mCi of Cs-137 and 44 mCi of AmBe. KY Event Report ID No.: KY160008 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.

| ENS 47839 | 16 April 2012 14:22:00 | The licensee notified the Kentucky Department of Public Health and Safety, Radiation Health Branch on April 16, 2012 at 1135 (CDT) of a missing static eliminator. The static eliminator was discovered to be missing by an oncoming operator on April 13, 2012 at 0700 (CDT). An operator on the previous shift reported the device to be in place. The Director of Facility Operations was not in the office on April 13, 2012 and was not made aware of the missing device until April 16, 2012 at 0715 (CDT). The licensee initiated a search for the device on April 16, 2012 at 0715 (CDT) but has been unsuccessful in locating the device. The licensee plans to continue searching for the device. The licensee does not suspect tampering or theft and no exposures to personnel have occurred or are expected at this time. The device is a Model P-2021 Static Eliminator, Serial # A2HU670, with a 10 mCi Po-210 source. Kentucky Radiation Health Branch Report number KY120007. No other notifications have been made by the licensee. THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL Category 3 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf Note: This device is assigned an IAEA Category 3 value based on the actual radioactivity of the source, not on the device type.

| ENS 47217 | 30 August 2011 10:56:00 | Kentucky Radiation Health Branch was notified on 08/08/2011, by a representative from Patriot Engineering and Environmental, Inc. of a vehicle running over a portable gauge on Saturday morning, 08/06/2011. The gauge was run over by an excavator during backfill operation. The gauge is identified as Humboldt Model 5001 EZ, serial no. 3260, containing 11 mCi of Cs-137 and 44 mCi of Am-241/Be. Surveys of the damaged gauge taken by the licensee indicated that the source had not been breached and that there was no leakage. Kentucky Event Report ID No: KY110006 |
