Radiation detector with europium-doped calcium fluoride scintillation crystal with special light-emitting surface

Abstract

The invention relates to a radiation detector with a scintillation crystal with a special light-emitting surface. A shape of the light-emitting surface of the scintillation crystal is optimized, an optical light guide structure is formed by a light-emitting end of a scintillator, the specific shape design considers the matching between the refractive index and the light-emitting wave band of the scintillation crystal, the light-emitting probability of the emergent light which is totally reflected and emitted for the first time in the prior art can be increased, the measurement efficiency and the measurement precision are improved, and the detection performance can be further improved particularly when a high-performance detector is developed.

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...
