Title	Missing Two Krypton-85 Thickness Gauges
Event Description	Saint-Gobain Performance Plastic located in Hoosick, NY, said that they are missing two 500 millicurie Kr-85 thickness gauges (500 millicuries in 1967, half life 10.4 years) from their Saint-Gobain Performance Plastic company in New Haven, CT, which was closed in late 2003 or early 2004. The Kr-85 thickness gauges license number is 20-01382-02 (license expired in 1994 and were licensed through LFE Industrial System Corp.). Caller stated that the krypton thickness gauges were not licensed through the State of New York but to CT which is an NRC non-agreement state. On 09/26/05 the two krypton thickness gauges were discovered missing while putting together an ionizing radiation report for the State of CT for the radioactive materials that were located in their New Haven facility. The two krypton thickness gauges were made by LFE Tracer Units (now known as EGS Gauging located in MA) and each contained 500 millicures of Kr-85 as of 1967. Based on a total of activity 1000 millicuries for the two Kr-85 thickness gauges at the end of 1968 as of 2005 the total activity of the two thickness gauges would be around 85 millicuries (37years, half life 10.4 years). Model number of the two gauges are S-6A and their serial numbers are 24A & T9A.
