A radiation detection apparatus includes a scintillator, a photoelectric conversion unit, and a grid for removing scattered radiation. The photoelectric conversion unit includes a plurality of pixels arranged in a two-dimensional array on a substrate. Each pixel is configured to convert visible light output from the scintillator into an electric signal. The grid, the substrate, the photoelectric conversion unit, and the scintillator are disposed in this order from a radiation-incident side of the radiation detection apparatus to an opposite side thereof. In this radiation detection apparatus in which the scintillator is disposed on the side opposite to the radiation-incident side, scattered radiation is effectively removed. |
