ＣＴ用放射線検出器。At least three scintillators are arranged side by side with a radiation shielding member interposed between them and delivered in one housing, one photomultiplier tube is placed on the boundary of each scintillator, and the scintillators are placed on both sides of the boundary. The sum of the outputs of two or more photomultiplier tubes that are optically coupled and arranged in a total is analyzed by one wave height analyzer, and the AND condition of the output and the output of each photomultiplier tube is determined. The present invention is characterized in that the presence or absence of an output from each photomultiplier tube is determined based on whether or not the condition is satisfied, and it is also determined which scintillator is used to emit light based on the presence or absence of an output from each photomultiplier tube. E
