Model 977 Series Wide Range Ion Chamber Detectors
Ion Chamber detectors are similar to capacitors, with two electrodes separated by a volume of air. The detector is a gamma sensitive radiation detection device, which measures radiation in the range of 1 x 10-1 mR/h to 1 x 107 mR/h with an energy dependence of less than ± 10% from 60 keV to 3 MeV. The preamp is housed in a gasket sealed enclosure. Interconnection between the detector and preamplifier is accomplished via two five foot cables, encased in a flexible conduit.
