Abstract
A radiographic element is disclosed comprised of a film support capable of transmitting radiation to which the radiographic element is responsive having opposed major surfaces, and, coated on the opposed major surfaces, spectrally sensitized high tabularity tabular grain emulsion layer units, and, interposed between each of the emulsion layer units and the support, means for absorbing radiation to which said emulsion layer units are responsive. The emulsion layer units exhibit a coefficient of variation of less than 15 percent, based on the total grain population having an equivalent circular diameter of greater than 0.1 .mu.m, and greater than 97 percent of the projected area of grains having an equivalent circular diameter of greater than 0.1 .mu.m is accounted for by tabular grains having a mean thickness of less than 0.3 .mu.m and a halide content of from 0 to 5 mole percent chloride, from 0 to 5 mole percent iodide, and from 90 to 100 mole percent bromide, based on total silver.
