In a method for preparing a radiation image storage panel comprising a support and a stimulable europium-activated cesium halide phosphor layer formed on the support by heating an europium-activated cesium halide phosphor or sources for production of the europium-activated cesium halide phosphor under reduced pressure to evaporate the phosphor or phosphor source and depositing the evaporated phosphor or phosphor source on a substrate, the deposition is preferably performed under the condition that a relationship between a molar ratio of europium to cesium in the deposited stimulable phosphor layer and a temperature of the substrate satisfies all of the formulas (1) to (3): T>=867.24x<0.4537> Formula (1) T>=0.0985x<-1.0587> Formula (2) T<=485.4x<2>-760.75x+297.37 Formula (3) in which T represents the temperature of the substrate in term of ° C., and x represents a molar ratio of europium to cesium in the deposited stimulable phosphor layer.
