Abstract
Abstract A radiation detecting apparatus includes a pair of substrates disposed face to face in such a manner that a plurality of grooves provided in one of the facing surfaces at a predetermined interval face a plurality of grooves provided in the other of the facing surfaces at the predetermined interval. Radiation shielding plates are inserted at both ends thereof into a facing pair of grooves to be held by both of the substrates, scintillators are mounted on a corresponding one of the radiation shielding plates, and photodetectors are fixed to either one of the facing surfaces of the substrates between adjacent grooves so that a plurality of facing pairs of photodetectors are juxtaposed.
