ABSTRACT:
A radiation detector basically comprises a scintillator, a light guide for introducing scintillation light, and a photodetector for detecting the scintillation light. A light output portion of the scintillator is wedge-shaped, and a light input portion of the light guide is V-shaped in section so as to receive the wedge-shaped light output portion of the scintillator. With this arrangement, light reflection at the interfaces of the scintillator and light guide is reduced, resulting in an improvement of transmission efficiency of light.
