Radiation detector with cerium doped gadolinium silicate scintillation crystal having special light exiting surface

Abstract

The invention relates to a radiation detector with a scintillation crystal having a special light exiting surface. The shape of the light exiting surface of the scintillation crystal is optimized; anoptical light-conducting structure is formed through the exiting end of a scintillation body itself; the specific shape design thereof considers matching with the refractive index and the exiting waveband of the scintillation crystal itself; the exiting rate of exit light, which is totally reflected while exiting for the first time, in the prior art can be increased; the measurement efficiency and the measurement precision are increased; and in particular, when a high-performance detector is researched, the detection performance can be further improved.

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, gamma-ray radiation, particle radiation or cosmic ray radiation, and specifically to a scintillation detector in which the scintillator is crystal in the radiation intensity measurement. Background technique [0002] Radiation measurement has played an important role in many fields, such as nuclear power plant thermal power plant radiation measurement, continuous measurement of radiation dose at the measurement site; industrial and civil construction, construction decoration, construction material manufacturing, and radioactivity measurement of various construction materials; Geological prospecting, geological prospecting and mine radiation measurement; used for ray security inspection gates, which can help customs, airports, border inspections, and security inspections of important meeting places; radiation measureme...
