Abstract
Disclosed is a radiation image conversion panel wherein luminance is improved by preventing the disorder of the structure of phosphor columnar crystals, thereby eliminating the scattering and refraction of optical elements which is emitted by an X-ray-irradiated phosphor and propagated in the direction of a photoelectric conversion element. Moreover disclosed is a radiation image detector using the same. The radiation image conversion panel is characterized in that the radiation image conversion panel comprises a phosphor layer on the substrate, that the phosphor layer is configured of the phosphor columnar crystals formed from a phosphor matrix compound and an activator by vapor deposition, and that the degree of the orientation of the surface of the phosphor columnar crystals, the degree of the orientation being based on X-ray diffraction spectrum and the surface having a fixed mirror index, is in the range of 80 to 100% without regard to the position in the direction of the thickness of the layer from the root near the substrate to the tip of the phosphor columnar crystals of the phosphor layer.
