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 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. The tabular silver halide grains are spectrally sensitized using a combination of spectral sensitizing dyes to provide increased speed and reduced dye stain. The dyes have maximum J-aggregate absorptions on the tabular silver halide grains of from about 380 to about 500 nm, wherein the maximum J-aggregate absorption of one spectral sensitizing dye is from about 20 to about 50 nm lower in wavelength than the maximum J-aggregate absorption of the second spectral sensitizing dye.

An imaging assembly includes 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 m, and comprise at least 90 mol % bromide and up to 4 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. The film is used in combination with one or more intensifying screens that absorb X-radiation and emit radiation having a wavelength of from about 300 to about 500 nm. In many embodiments, the intensifying screens include a “blue-light” emitting alkaline earth fluorohalide phosphor dispersed in a binder on a support.

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 M, and comprise at least 90 mol % bromide and from about 0. 5 to about 2. 75 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. In addition, the tabular grain emulsion includes a mercapto-substituted benzothiazole, benzoxazole, or benzimidazole to provide desired image tone and processability.

A radiographic silver halide film has reduced yellow dye stain by including a blend of tabular silver halide grains in the emulsion layers. The blend of grains includes blue-sensitive tabular silver halide grains that have an aspect ratio of at least 15, a grain thickness of at least 0. 1 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 blend also includes green-sensitive tabular silver halide grains that have an aspect ratio of at least 20, a grain thickness of at least 0. 07 m, and comprise at least 90 mol % bromide, up to 1. 5 mol % chloride, and up to 1. 5 mol % iodide, based on total silver halide.
