This invention relates to a double side radiographic element which comprises a support and at least two silver halide emulsion layers coated on each side of said support, wherein said at least two silver halide emulsion layers show a speed difference of at least 0.3 logE and are both sensitive to the same region of the electromagnetic spectrum, and wherein said double side radiographic element shows a sensitometric curve having a toe contrast value higher than 0.45 and an average contrast higher than 1.40. A symmetrical radiographic assembly comprising intensifying screens and the above described radiographic element and a process for obtaining a radiographic image from the radiographic assembly are also disclosed.
