Model 943 Series Gamma Scintillation Detectors
The Model 943 Series Gamma Scintillation Detectors consist of an integral gamma sensitive NaI crystal, a photomultiplier tube, a preamplifier assembly, and various interconnecting cables for connecting the detector, ratemeter, and power supply. All are functionally identical. The size of the crystal employed, the housing material, Light Emitting Diode (LED) check source, and whether or not an Americium source is included in the assembly are the only differences. All photomultiplier tube/crystal assemblies are of integral line construction.
