Patent ID: 7372046

Claim:
A radiation image conversion panel comprising a support and provided thereon, a stimulable phosphor layer containing a stimulable phosphor in a polymer resin, wherein a luminescence intensity ratio of stimulable phosphor particles comprising a smallest average particle diameter to stimulable phosphor particles comprising a largest average particle diameter is 0.8-1.2, provided that a total average particle diameter of all the stimulable phosphor particles is 3.0-10.0 μm, an average particle diameter of the stimulable phosphor particles comprising a smallest average particle diameter is 2.0-6.0 μm, an average particle diameter of the stimulable phosphor particles comprising a largest average particle diameter is 6-15 μm, and a content of the stimulable phosphor particles comprising a smallest average particle diameter or the stimulable phosphor particles comprising a largest average particle diameter is within the range of at least 10% by weight and at most 90% by weight, based on the total stimulable phosphor content.
