Abstract

The invention relates to a scintillating crystal radiation detector plated with a high reflecting film and a special light-out surface. According to the detector, the conception of performing pertinent film design according to a main transmitting waveband of a scintillating crystal itself is adopted, and the difficulties that the data volume is excessively large and analysis is not easy in thin film research are overcome; an appropriate reflecting film material is obtained, the material has adhesive force as good as the crystal, and film layers are small in quantity and easy to realize; and special light-out surface design matched with a total-reflection film plating scheme is further provided, and measurement efficiency and measurement precision are improved accordingly.
