Abstract
A radiation detection apparatus including a scintillator layer configured to convert radiation into light; a light sensor layer including a plurality of light sensors configured to detect light emitted from the scintillator layer; and a reflection layer configured to reflect light emitted from the scintillator layer. The scintillator layer is arranged between the light sensor layer and the reflection layer. The following condition is satisfied:0.375≤(100−)/(100−(%))<3.75where the average conversion efficiency in a region of 25% of the thickness of the scintillator layer from a reflection layer side is set to 100 as a reference, x is the average conversion efficiency in a region of 25% of the thickness of the scintillator layer from a light sensor layer side, and y (%) is the reflectance of the reflection layer.
