PROBLEM TO BE SOLVED: To provide a configuration in which a function of detecting a radiation is provided separately from a function of detecting the radiation as an image without great increases in panel size and thickness nor decreases in image detection sensitivity and radiation detection precision.SOLUTION: A radiation detection panel is provided with a scintillator 71 which absorbs a radiation and then emits light, and a radiation detector 60 having pixel parts 74, each including a photoelectric conversion part 72, a storage capacitor 68, and a TFT (Thin Film Transistor) 70, arranged on an insulating substrate 64 in a matrix. The insulating substrate 64 is made transmissive to light, a radiation detection part 62 which is made of an organic photoelectric converting material, converts light emitted from the scintillator 71 into an electric signal, and outputs the electric signal is provided on the opposite side from the scintillator 71 across the radiation detector 60 (an upstream side in an arriving direction of the radiation), and a partial reflection layer 170 which transmits part of incident light through holes bored in a reflection surface and is made different partially in boring density of the holes in the reflection surface is provided between the radiation detector 60 and radiation detection part 62.COPYRIGHT: (C)2012,JPO&INPIT【課題】放射線を画像として検出する機能と別に放射線を検出する機能を設けた構成を、パネルサイズの大型化や厚みの大幅な増大、画像検出感度の低下や放射線検出精度の低下を招くことなく実現する。【解決手段】放射線を吸収して発光するシンチレータ71と、光電変換部72、蓄積容量68及びTFT70を備えた画素部74が絶縁性基板64上にマトリクス状に配置されて成る放射線検出器60と、が設けられた放射線検出パネルにおいて、絶縁性基板64に光透過性をもたせると共に、放射線検出器60を挟んでシンチレータ71と反対側(放射線の到来方向上流側)に、有機光電変換材料から成り、シンチレータ71から放出された光を電気信号へ変換して出力する放射線検出部62を設け、放射線検出器60と放射線検出部62の間に、反射面内に穿設された孔により入射光の一部を透過させ、孔の穿設密度が反射面内で部分的に相違された部分反射層170を設ける。【選択図】図4
