摘要： Radiographic silver halide emulsions are provided comprising silver halide grains the average silver halide grain diameter of which is at least 250 nm and which consist substantially of silver bromide dispersed in a hydrophilic colloid binder e.g. gelatin wherein the silver halide grains have high primitive surface sensitivity for direct exposure to penetrating radiation and are substantially regular in shape and wherein the ratio of hydrophilic colloid to silver halide is at most about 1.0. These emulsions have high sensitivity for direct exposure to penetrating radiation and are themselves substantially insensitive to formation of pressure marks upon rapid processing.
