Title	Agreement State - Lost Category 4 Source
Event Description	The following information was provided by the Ohio Department of Health (ODH) via email: ODH received a notification last night [on 26 October, 2023], that NDC Technologies, Inc. (NDC) discovered a 25 mCi Americium-241 (Am-241) source was missing from their inventory. NDC is located in Dayton. The licensee has conducted three inventories of all sources, reviewed all shipping logs, and have searched (both visually and with a survey meter) areas, floors, and drawers where devices are built and stored. The source may have mistakenly been put into a trashcan or sent, still mounted in the sodium iodine crystal, for disposal. The last disposal was on July 12, 2023, and the licensee has contacted the disposal company and will speak with them further today. ODH will be sending an inspector to further investigate. NMED report number: OH230010 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.
