A radiation image storage panel comprises a stimulable phosphor layer, which
contains
a stimulable phosphor, and a transparent protective layer overlaid on the stimulable
phosphor layer. The transparent protective layer has a layer thickness of at most
50 m and comprises at least four layers formed on a transparent protective
layer support for supporting the transparent protective layer, the at least four
layers comprising transparent inorganic layers and organic layers, which are located
alternately. Each of the transparent inorganic layers contains a compound selected
from the group consisting of a metal oxide, a metal nitride, and a metal oxynitride,
and is formed with a vacuum deposition technique. Each of the organic layers is
formed with a coating technique or a vacuum deposition technique.
