Section: claims

1. A radiation image storage panel, comprising: a substrate; CD  a stimulable phosphor layer containing a stimulable phosphor; and  a light reflecting layer arranged between the substrate and the stimulable phosphor layer,  wherein the light reflecting layer contains a light reflecting substance, and  wherein a scattering length of the light reflecting layer with respect to light having wavelengths falling within a stimulation wavelength range for the stimulable phosphor is at most 5 xcexcm. 2. A radiation image storage panel as defined in  claim 1  wherein the light reflecting substance is a white pigment. claim 1 3. A radiation image storage panel as defined in  claim 2  wherein the light reflecting substance has a bulk density of at most 1 mg/cm 3 . claim 2 4. A radiation image storage panel as defined in  claim 3  wherein the light reflecting substance has a BET specific surface area of at least 1.5 m 2 /g. claim 3 5. A radiation image storage panel as defined in  claim 2  wherein the light reflecting substance has a BET specific surface area of at least 1.5 m 2 /g. claim 2 6.
