Blue-sensitive film for radiography and imaging assembly and method

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 at least 15, a grain thickness of at least 0.1 mu m, and comprise at least 90 mol % bromide and up to 4 mol % iodide, based on total silver halide. Substantially all of the iodide is present in an internal localized portion of the tabular silver halide grains that excludes the surface of the grains. 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.
