ABSTRACT:
A silver halide photographic material has at least one photosensitive silver halide emulsion layer and at least one non-photosensitive hydrophilic colloid layer on a support. The silver coverage per surface is 1.0-2.2 g/m.sup.2. The silver halide emulsion layer contains silver halide grains wherein tabular silver halide grains having an aspect ratio of at least 5 account for at least 50% of the entire projected area of silver halide grains. The silver halide grains have been grown on pure silver bromide or silver chlorobromide grains as nuclei so as to form silver iodobromide or silver chloroiodobromide having a silver iodide content of 0.1-3.20 mol % at the end of growth. This X-ray photosensitive material having high sensitivity and sharpness is used with a regular screen.
