Abstract
An improvement of a radiation image detecting apparatus composed of a phosphor screen that converts radiation into visible light and a two-dimensionally extended photo-detector placed on one surface of the screen, resides in that the phosphor screen is composed of a partition that divides the screen on its plane to give small sections and phosphor-incorporated areas that are sectioned with the partition. The phosphor-incorporated areas and the partition scatter the visible light with scattering lengths of 20 to 200 &mgr;m and 0.05 to 20 &mgr;m, respectively, providing that a ratio of the former to the latter is 3.0 or higher, and each of the phosphor-incorporated areas and the partition absorbs the visible light with an absorption length of 1,000 &mgr;m or longer.
