Abstract
A radiation detection apparatus comprises a rectangular sensor panel having a pixel array including a plurality of photoelectric conversion elements, and a scintillator layer on which a plurality of columnar crystals configured to convert radiation into light are arranged. The scintillator layer has one side along an outer shape of the sensor panel and an opposite side of the one side and a region between the one side and the opposite side in which directions in which columnar crystals extend and a normal line of a main surface of the sensor panel form angles. The angles have a concentric angle distribution decreasing in angle from a central portion of the one side toward the opposite side, and thicknesses of the plurality of columnar crystals have a concentric thickness distribution increasing in thickness from the central portion of the one side to the opposite side.
