Abstract
Radiographic elements are disclosed with silver halide emulsion layer units coated on opposite sides of a film support. The radiographic elements are constructed to reduce crossover during exposure by intensifying screens to minimal levels. To permit the minimal crossover radiographic elements to be employed with varied intensifying screens, one of the silver halide emulsion layer units over an exposure range of at least 1.0 log E exhibits an average contrast of from 0.5 to <2.0 and point gammas that differ from the average contrast by less than .+-.40% and the second silver halide emulsion layer unit exhibits a mid-scale contrast of at least 0.5 greater than the average contrast of the first silvert halide emulsion layer unit.
