High speed reflective radiographic material

A reflective radiographic material having a speed of at least 800 and comprising a reflective resin-coated paper support that has first and second major surfaces, said reflective radiographic material having disposed on said first major reflective support surface, two or more hydrophilic colloid layers including a single silver halide emulsion layer,

• said single silver halide emulsion layer comprising tabular silver halide grains that have an aspect ratio of from about 25 to about 40, an average grain diameter of from about 2.5 to about 4.5 μm, and an average thickness of from about 0.07 to about 0.11 μm, and comprise at least 95 mol % bromide and up to 1 mol % iodide, both based on total silver in said grains,
• said material optionally comprising a protective overcoat disposed over all of said hydrophilic colloid layers,
• wherein said tabular silver halide grains in said silver halide emulsion layer are dispersed in a hydrophilic polymeric vehicle mixture comprising from about 0.1 to about 1.5% of deionized oxidized gelatin, based on the total dry weight of said hydrophilic polymeric vehicle mixture,
• the coverage of silver in said silver halide emulsion layer is from about 15 to about 18 mg/dm and the polymer vehicle coverage in said silver halide emulsion layer on said first major reflective support surface of from about 38 to about 40 mg/dm2.
