Although all the Model 897A Series GM Detectors are functionally identical, the detectors differ in the tube type employed, sensitivity, and housing. The GM detector has preamplifier circuitry located in the interior of the overall protective housing. The preamplifier provides pulse conditioning and cable driving capabilities to match the input characteristics of the ratemeter.
- Rugged, Reliable Radiation Detector
- Personnel Protection
- Factory NIST Traceable Calibration
- Field Proven Design
- For Use with Model 956A Digital Readout or Model 960 Series Digital Radiation Monitoring System (DRMS)
Area monitoring is used for the detection of x-ray or gamma radiation in a selected area. The monitor should be used in any location where personnel may be exposed to an adverse amount of radiation. Applications include nuclear reactors, accelerators, hot cells, irradiators, and any area where radiation sources are handled. These monitors can be used as single channel monitors or grouped together as a multichannel area monitoring system.
