PROBLEM TO BE SOLVED: To provide a radiation image conversion panel that can reduce damages by use and can be used in a curved state.SOLUTION: A radiation image conversion panel 10 includes a flexible support 1, a photostimulable phosphor layer 2 disposed on a surface 1a of the support 1 and comprising a plurality of columnar crystals 25, a first protective film 3 disposed on the photostimulable phosphor layer 2, and a second protective film 4 disposed on the first protective film 3. The photostimulable phosphor layer 2 is composed of a photostimulable phosphor comprising CsBr doped with Eu. The first protective film 3 covers an upper face 2a and a side face 2c of the photostimulable phosphor layer 2. The second protective film 4 has a pencil hardness scale equal to or lower than a pencil hardness scale of the first protective film 3. The panel has enough flexibility to prevent fracture in the second protective film 4 even when the panel is bent to have a radius of curvature of minimum 15 mm.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】使用による損傷を低減可能であるとともに、湾曲した状態での使用を可能とする。【解決手段】放射線像変換パネル10は、可撓性を有する支持体1と、支持体1の表面1a上に設けられ、複数の柱状結晶25からなる輝尽性蛍光体層2と、輝尽性蛍光体層2上に設けられた第1保護膜3と、第1保護膜3上に設けられた第2保護膜4と、を備え、輝尽性蛍光体層2は、EuをドープしたCsBrを含む輝尽性蛍光体から構成され、第1保護膜3は、輝尽性蛍光体層2の上面2a及び側面2cを覆い、第2保護膜4の鉛筆硬度は、第1保護膜3の鉛筆硬度以下であり、曲げ半径が最小で15mmまで湾曲させても第2保護膜4の破断が生じない可撓性を有する。【選択図】図1
