Abstract (en)

A radiographic element comprises a support having disposed on each side thereof, a silver halide emulsion unit that comprises silver halide grains and a gelatino-vehicle. The silver halide grains comprise at least 95 mol% bromide based on total silver, at least 50% of the silver halide grain projected area being provided by tabular grains having an average aspect ratio greater than 8. The grains also have a thickness that is no greater than 0.10 mu m and an average grain diameter of from about 1.5 to about 3 mu m. The coverage of silver in each silver halide emulsion unit is no more than 11 mg/dm<2>, and the coverage of the gelatino-vehicle in each silver halide emulsion unit is no more than 11 mg/dm<2>.
