Abstract
An X-ray image intensifying screen is described comprising halide-containing phosphor particles. In order to improve the stability to moisture and thus to protect against loss of fluorescence power the phosphor particles are admixed with, combined with or have reacted with one or more organic substances that are capable of reacting with hydrogen chloride and/or labile halogen. The stability is further improved by admixture of nonhygroscopic halide-free phosphor particles in such a ratio that the ratio of the intensification factor of said screen with respect to the intensification factor of said screen but containing no such halide-free phosphor particles is not smaller than 1:4.
