Bismuth germanate scintillating crystal radiation detector plated with high reflecting film and special light-out surface

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.

Description

technical field [0001] The present invention relates to the measurement of nuclear radiation or X-ray radiation, in particular to the measurement of X-ray radiation, γ-ray radiation, particle radiation or cosmic ray radiation, in particular to a scintillation detector in which the scintillator is a crystal in radiation intensity measurement. Background technique [0002] Radiation measurement has played an important role in many fields, such as nuclear power plant radiation measurement, continuous measurement of radiation dose at the measurement site; industrial and civil buildings, building decoration, production and manufacturing of building materials, radioactivity measurement of various building materials; Geological exploration, geological prospecting and mine radiation measurement; used for ray security inspection access doors, which can provide assistance for customs, airports, border inspections, and security inspections of important meeting places; radiation measurem...
