Abstract
A radiographic assembly comprising: a radiographic element which comprises a support and a front and back pair of silver halide emulsion layers coated on the opposite sides of the support, and a front and back pair of intensifying screens adjacent said front and back emulsion layers, respectively, wherein at least one of said silver halide emulsion layers shows a swelling index lower than 140% and a melting time of from 45 to 120 minutes, and the contrast difference between said pair of silver halide emulsion layers is at least 0.5, wherein the X-ray stimulated light emission difference between said pair of intensifying screens is at least 0.6 IogE, and wherein the average imagewise cross-over of said radiographic element is lower than 5% at optical density of from 0.5 to 1.75 and in the range of from 5 to 15% at optical density of from 1.75 to 3.25, said imagewise cross-over being measured according to the formula described in the specificaton.
