A radiation imaging apparatus includes an attenuation member on the back surface side opposite the radiation incident surface of a radiation detection unit. The attenuation member is configured to reduce unexpected appearance of a part disposed on the back surface side of the radiation imaging apparatus, the unexpected appearance of which occurs due to backscattered radiation reflected by the structured part on the back surface side of the radiation imaging apparatus. The attenuation member includes a material having a radiation transmittance higher than that of the part and covers the end portion of the outline of the part that overlaps the radiation detection unit in orthogonal projection onto the surface opposite the incident surface of the radiation detection unit, and the area of the attenuation member is smaller than that of the radiation detection unit.

A ray detector substrate includes: photodetectors including first photodetectors and second photodetectors; and dimming portions including, at a side of each first photodetector away from a substrate, a respective first dimming portion, and, at a side of each second photodetector away from the substrate, a respective second dimming portion. A second scintillator layer is configured to convert part of rays into a first radiation fluorescence. A first scintillator layer is configured to convert another part of the rays into a second radiation fluorescence. The first dimming portion is configured to reflect the second radiation fluorescence, and to enable the first radiation fluorescence to pass through the first dimming portion to be detected by the first photodetector. The second dimming portion is configured to reflect the first radiation fluorescence, and to enable the second radiation fluorescence to pass through the second dimming portion to be detected by the second photodetector.

An object of the present invention is to enable a scintillator panel of a type having a barrier rib to have sufficient mechanical strength and enhanced brightness.

A radiological image conversion panel, having a phosphor layer containing therein a fluorescent substance which emits light through radiation exposure, is manufactured by forming the fluorescent substance into respective columnar structures on one of surfaces of a substrate to thereby obtain a phosphor layer made up of a group of columnar structures. The panel is subsequently manufactured by forming reflection films by respectively covering an outer surface of each of the columnar structures with a reflection film while leaving a gap between respective adjoining columnar structures, the reflection film being arranged to reflect light of a predetermined wavelength. In case a refractive index of the gap is lower than a refractive index of the columnar structures, the reflection films are formed of an inorganic material having a higher refractive index than the refractive index of the columnar structures.

The internal optical fiber may detect photons emitted during ionization avalanche events triggered by incident radiation. Such a radiation detector may include a housing, a fill gas within the housing, and an optical fiber within the housing. The fill gas may interact with radiation through an ionization avalanche that produces light. The optical fiber within the housing may capture the light and transmit the light out of the housing.
