The following was received via email:
General licensee (GL) reported to BRP (Bureau of Radiation Protection) on 12/18/09 that a generally licensed device was unaccounted for. The device has been identified as an Industrial Dynamics FilTech FT-50 [fixed gauge] level indicator, serial number 113216, containing 100 mCi of Am-241.
The licensee last reported that the device was in their possession with the annual GL registration to BRP on 10/11/02. The device was not listed on the next GL registration submitted by the licensee on 11/26/03. During an internal audit by the licensee it was determined that a report of disposition of the device had not been submitted to BRP. The device had been installed in a process line which was decommissioned and dismantled in June 2003. As the licensee investigated the matter they determined that they could not account for the current location of the device. The manufacturer had no record of receipt of the device and the licensee could not locate the device anywhere within their facility.
Additional investigation and information is being requested by BRP.

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.
