摘要：

To optimize characteristics of alpha-radiation detectors as well as those intended to stabilize gamma spectrometers, the alpha/gamma ratio has been studied for inorganic scintillation detectors within a wide temperature range (from -20 to +80 degrees C) and at various signal formation time values (from 0.2 to 20 mu s). Inorganic scintillators with high atomic numbers have been studied, namely, alkali halide and oxide crystals as well as a semiconducting single-crystal ZnSe(Te). Though the scintillators on the base of the oxide materials have satisfactory resolution and light output, they cannot be considered as efficient detectors of a-radiation due to a low alpha/gamma ratio (similar to 0.20). The most appropriate detector of a-radiation remains single crystalline CsI(TI) having the best scintillation characteristics, nonhygroscopic, convenient to use and comparatively cheap.
