A scintillator module includes a substrate, a columnar scintillator crystal layer formed on the substrate, and a non-adhesive moisture-proof member having a given hardness and opposing a crystal growing side of the columnar scintillator crystal layer. The moisture-proof member ensures a void between the moisture-proof member and individual conic peak portions of columnar scintillator crystals forming the columnar scintillator crystal layer under vacuum sealing, and holds the columnar scintillator crystal layer in a moisture-proof state between a moisture-proof layer and the substrate.

According to an embodiment, a radiation-scintillated shield which attenuates an incident radiation, includes a shielding part containing an activator-added gadolinium compound as an aggregate. The activator uses the gadolinium compound as a base material and emits light when struck by the radiation. Consequently, it becomes possible to shield a γ-ray and a neutron with a thickness which is about the same as that of a conventional concrete shield of γ-ray shield, and to confirm leakage of radiation.

A radiation image reading device includes: a light scanning unit; a light detection unit. Each of a transmittance when the excitation light reflected from the surface of the recording medium is transmitted through the optical filter and a transmittance when the signal light emitted from the surface of the recording medium at an angle larger than a predetermined angle with respect to a direction perpendicular to the scan line within the detection surface is transmitted through the optical filter is smaller than a transmittance when the signal light emitted from the surface of the recording medium at an angle smaller than the predetermined angle with respect to a direction perpendicular to the scan line within the detection surface is transmitted through the optical filter.
