Abstract
A radiation detector is provided with a scintillatorA containing a plurality of modified regionsand a plurality of photodetectors or a position-sensitive photodetector optically coupled to a surface of the scintillatorA. The plurality of modified regionsare formed by irradiating an inside of a crystalline lump which will act as the scintillatorA with a laser beam and three-dimensionally dotted and have a refractive index different from a refractive index of a surrounding region within the inside of the scintillatorA.
