A radiation imaging apparatus including: a plurality of conversion elements being arranged in one-dimensional or two-dimensional array on a substrate, and converting an incident radiation into an electric signal; and a light source for calibration emitting a light to the conversion elements. During a light output adjustment period for driving the light source, a driving level of the light source is adjusted based on a control signal produced by comparing an output signal from a conversion element with a predetermined initial output signal.

A radiation detecting apparatus includes a sensor panel 100, a phosphor layer 111 formed on the sensor panel 100 to convert a radiation into light, and a phosphor protecting member 110 covering the phosphor layer 111 to adhere closely to the phosphor protecting member 110. The phosphor protecting member 110 includes a phosphor protecting layer 116 made of vapor deposition polymerization polyimide formed by vapor deposition polymerization, a reflecting layer 113 reflecting the light converted by the phosphor layer 111, and a protecting layer 117 made of vapor deposition polymerization polyurea formed by the vapor deposition polymerization. By such a configuration, a polymerization reaction of the phosphor protecting layer 116 is performed on the substrate. Thereby, the generation of by-products is suppressed to make it easy to acquire the uniformity of film quality. Consequently, the generation of a situation in which structural disorders are generated on the reflection surface of the reflecting layer 113 to cause image defects can be suppressed.

A radiation detecting apparatus having: a substrate; a phosphor layer which is formed on a principal plane of the substrate and converts a wavelength of a radiation; and a phosphor protective member including a phosphor protective layer which covers the phosphor layer and is adhered to the substrate, wherein the phosphor protective layer is made of a hot melt resin and an upper surface and a side surface of the phosphor layer and at least a part of at least one side surface of the substrate are covered with the phosphor protective layer. Thus, a moisture-proofing effect for penetration of the moisture from an interface between the phosphor layer and the substrate on the side surface side of the substrate can be improved. Further, by using the hot melt resin for the phosphor protective layer, simplification of manufacturing steps, remarkable reduction in the number of working steps, and remarkable reduction in costs of a product can be accomplished.

By using such a scintillator protection layer, a film formation time of the scintillator protection layer can be shortened, and the film thickness dispersion of the scintillator protection layer can be suppressed. Moreover, the adhesion property to the scintillator foundation layer and to the reflective layer protection layer can be improved.
