Claim:
1. A method for producing a radiation detector comprising pluralities of first and second cells constituted by scintillators having different compositions for different detection sensitivity distributions of radiation energy, pluralities of light-receiving elements each receiving light emitted from each of the first and second cells by radiation to convert the light to electric signals, and reflective layers for guiding the light emitted from said first and second cells to said light-receiving elements, comprising a step of forming a first cell array having at least m×n first cells bonded by said reflective layers from a first scintillator plate, wherein m and n are natural numbers of 2 or more, which may be the same or different; a step of forming a second cell array having at least m×n second cells bonded by said reflective layers from a second scintillator plate having a different composition from that of the first scintillator plate; a step of cutting said first cell array to obtain at least n first single arrays each comprising at least m×1 first cells bonded by said reflective layers; a step of cutting said second cell array to obtain at least n second single arrays each comprising at least m×1 second cells bonded by said reflective layers; a step of aligning each first single array of one composition and each second single array of another composition with a light-receiving element array having at least m×2 light-receiving elements, such that said first and second cells oppose said light-receiving elements; and a step of adhering said first single array and said second single array to said light-receiving element array such that said first single array and said second single array are placed side-by-side on said light-receiving elements.
