A representative for the Air Force Master … A representative for the Air Force Master Material License reported that two Americium-241 sources (SSDR NR-1129-D0102-S; Model M43A1) each with a curie content of less than 300 microCuries (less than 600 microCuries total) were determined to be missing from a storage location at the Tyndall Air Force Base in Florida. The sources are used in Chemical Agent Detectors. The date of last confirmed inventory of the sources was December of 2005. The RSO at Tyndall AFB recently changed and a new inventory was conducted at which time the sources were determined to be unaccounted for. The licensee states that there is information that indicates the sources have been transferred to another AFB but that this has not yet been confirmed.
