A blue-sensitive, radiographic silver halide film comprises a silver halide emulsion layer comprising predominantly tabular silver halide grains that have an aspect ratio of from 8 to 14.5, a grain thickness of from about 0.15 to about 0.3 &mgr;m, and comprise at least 90 mol % bromide and up to 6 mol % iodide, based on total silver halide. The tabular silver halide grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.5% of oxidized gelatin, based on the total dry weight of the polymeric vehicle mixture in the emulsion layer.
