する放射線検出装置。In a radiation detection device in which a large number of radiation detector bodies, each consisting mainly of a scintillator and a photomultiplier tube, are closely arranged in a ring shape around a subject, a pair of flat rings arranged opposite each other is placed on the outer periphery side. A scintillator ring in which a number of holes are formed in the radial direction between the flat rings by wedges fitted at intervals, and the scintillator is inserted into each hole, and a flat light shield that fixes the scintillator ring concentrically. a photomultiplier tube fixing ring located on the outer periphery of the scintillator ring and fixed concentrically to the light-shielding fixing ring, the photomultiplier tube being held in a state in which the photomultiplier tube is optically coupled to the scintillator; , a light-shielding cover that shields the scintillator and the photomultiplier tube from light with the light-shielding fixing ring, and an adjustment circuit for the photomultiplier tube disposed on the light-shielding fixing ring outside the light-shielding cover. A radiation detection device comprising:
