PROBLEM TO BE SOLVED: To achieve a configuration having a function for detecting radiation separately from a function for detecting the radiation as an image, without increasing the size and thickness of a panel and reducing image detection sensitivity.SOLUTION: A radiation detection panel includes a scintillator 71 absorbing the radiation and emitting light and a radiation detector 60 configured in such a manner that a photoelectric conversion part 72 converting the light emitted from the scintillator 71 into an electric charge and a pixel part 74 having a storage capacitance 68 for storing the electric charge and a TFT 70 turned on when the electric charge is read are arranged like a matrix on an insulation substrate 64. In the radiation detection panel, the insulation substrate 64 has light transmissivity and a radiation detection part 62 is provided on the side opposite to the scintillator 71 across the radiation detector 60 (upstream side in the arrival direction of the radiation), the radiation detection part 62 made of an organic photoelectric conversion material, converting the light emitted from the scintillator 71 into an electric signal and outputting it. A partial reflection layer 170 is provided between the radiation detector 60 and the 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増大、画像検出感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、シンチレータ71からから放出された光を電荷へ変換する光電変換部72、電荷を蓄積する蓄積容量68及び電荷読出時にオンされる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の間に部分反射層170を設ける。【選択図】図4
