Abstract
A radiation detector includes: a scintillator including a pair of end surfaces opposing each other in a first direction and one side surface coupling the end surfaces; a semiconductor photodetector including a semiconductor substrate; and a wiring member electrically connected to the semiconductor photodetector. A length of the scintillator in the first direction is longer than that of the scintillator in a second direction orthogonal to the one side surface. A length of the one side surface in the first direction is longer than a width of the one side surface in a third direction. The semiconductor substrate includes a plurality of photodetection regions disposed in a first portion and first electrodes and a second electrode disposed in a second portion. Each of the photodetection regions includes a plurality of avalanche photodiodes arranged to operate in Geiger mode and a plurality of quenching resistors.
