The 943-5 Process GM Detector is designed for the direct measurement of beta and gamma noble gas activity inventilation or exhaust ducts. Key Features Plug-in GM tube detector Integral pulse conditioning and driving preamplifier 30 to 40 mg/cm3 wall for beta and gamma detection Operates from 15 in Hg to +15 psig Provides up to 5,200 CPM/mR/h, 137Cs Drives up to 1,500 ft of cable Used with Model 942A UDR or Model 960 System Federal and state regulations specify the concentration of radioactive isotopes that may be released into an unrestricted area. Facilities that use, or have the potential for the generation of, radioactive materials are required to monitor release points for radioactive noble gasses. The Model 943-5 Process Geiger-Mueller (GM) Detector has been designed for the direct measurement of beta and gamma noble gas activity in ventilation or exhaust ducts. The GM detector is a thin-walled, gas filled radiation detector. In low background areas, the GM tube may be installed directly into the ventilation or exhaust duct. In higher background areas, a lead shielded in-line or off-line process radiation monitor is recommended. Detector efficiency is a function of the sampling geometry and detector used, and ranges from approximately 1 x 103 to 1 x 107 CPM/µCi/cc.
