An IP cover having a light-shielding property is detachably mounted on an IP. The IP includes a stimulable phosphor layer on one surface thereof. The IP cover is mounted on the stimulable phosphor layer so as to be closely attached to the stimulable phosphor layer. The IP and the IP cover include notches, and a part of an inspection target is inserted into the notches at the time of inspection. An IP unit is mounted on a blade welded portion of an impeller. Radiation is applied from a radiation irradiation device and a radiation image of the blade welded portion is recorded on the IP as a latent image. The IP cover is detached from the IP unit and the IP is set on a template. The IP is set at an image reading position of a radiation image reading device by the template, and the radiation image is read.

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.

The present disclosure relates to a detection layer on a substrate. For example, a detection layer may include perovskite crystals of the type ABX.sub.3 and/or AB.sub.2X.sub.4. A may include at least one monovalent, divalent or trivalent element from the fourth or a higher period in the periodic table and/or mixtures thereof. B may include a monovalent cation, the volumetric parameter of which is sufficient, with the respective element A, for perovskite lattice formation. X may be selected from the group consisting of anions of halides and pseudohalides. The layer may have a thickness of at least 10 μm.
