A dual-coated radiographic element capable of producing a viewable image when heated following imagewise exposure is disclosed comprised of, on opposite sides of a transparent film, layer units containing radiation-sensitive radiation-sensitive silver halide grains, a light-insensitive source of silver, and a reducing agent for said light-insensitive reducible source of silver. Greater than 50 percent of total projected area of said silver halide grains being provided by tabular grains (a) having {100} major faces, (b) containing greater than 70 mole percent chloride, based on silver, (c) exhibiting an average thickness of less than 0.3 mu m, and (d) exhibiting an average equivalent circular diameter of greater than 0.6 mu m. |
