Abstract
Abstract A radiation image storage panel has at least one stimulable phosphor layer, and one or more layers provided on the stimulating rays incidence side of the stimulable phosphor layer. The latter layers respectively satisfy the condition of dav×μ<λ/2 or dav×μ>λ, wherein dav designates the average thickness of the layer, μ designates the refractive index of the layer, and λ designates the wavelength of stimulating rays.
