Standard detectors, usually based on alkali halide scintillators, are used for registration and gamma radiation spectrometry in the photons energy range from 50 keV under the influence of a radioactive source as well as for kitting of measurement devices for ionizing radiation of general purpose. Standard detector consists of a scintillation crystal hermetically packed in to aluminum, stainless steel or titanium container with UV transmitting protective glass. Special low-mass entrance windows are also available. Scintillation crystal is wrapped with reflecting material for maximum light collection. If the customer has a unique application, we can provide custom-made or special designs to ensure the optimal performance.
