Radiation image storage panel

摘要

A radiation image storage panel comprises a substrate and a stimulable phosphor layer, which is overlaid on the substrate and emits light in proportion to the amount of energy stored thereon during its exposure to radiation when it is exposed to stimulating rays. The substrate is constituted of a material, which transmits the light emitted by the stimulable phosphor layer and absorbs and/or scatters light having wavelengths falling within a stimulation wavelength range for the stimulable phosphor layer. The light having wavelengths falling within the stimulation wavelength range is thus prevented from passing or propagating through the substrate, and the signal-to-noise ratio of an image signal detected from the radiation image storage panel is thereby prevented from becoming low.
