Standard Detectors

Standard Detectors Nomenclature  

Standard Detectors  Standard detectors with NaI(Tl), CsI(Tl) and CsI(Na) are produced in several modifications. In all cases, the scintillator is a solid cylinder, having a butt surface adjacent to the glass output window of the container.

 Intended application: components of instruments for ionizing radiation measurements.

 The standard detector types in serial production and scintillation crystal dimensions are given in the Table below.

 All crystals are sealed in aluminium housings. Copper or stainless steel housings are available when your needs require low-background detectors.
