PROBLEM TO BE SOLVED: To provide a radiation image conversion panel with increased sensitivity in the radiation image conversion panel used for a radiation image recording/reproducing method utilizing a storage phosphor. SOLUTION: In the radiation image conversion panel having a phosphor layer formed by a gaseous depositional method, the phosphor layer is formed of an europium actived hologenated cesium based stimulable phosphor. In the ultraviolet exciting light emitting spectrum of the phosphor layer, the ratio S (470-500) of a light emitting amount by light emitting components showing light emitting peaks at 470 to 500 nm to all light emitting amount is within the range of S (470-500) < 0.35. In addition, the radiation image conversion panel emitting the light of 400 to 420 nm at the ratio S (400-420) of 0 < S (400-420) < 0.20 indicates a higher sensitivity. COPYRIGHT: (C)2004,JPO&NCIPI
