A reflective radiographic material is useful to provide images that can be viewed without a light box. This reflective radiographic material has a reflective support and a silver halide emulsion on one side of the support only. The material can be used with a single green- or blue-light emitting fluorescent intensifying screen as part of an imaging assembly. The reflective support enables the image in the radiographic material to be viewed without a light box and the speed of the material enables the use of low power X-radiation generating equipment.

Photographic silver halide materials containing an incorporated black-and-white developing agent can be quickly and simply processed using unique processing compositions and methods. In a “two-step” method, the exposed material is contacted with an alkaline activator solution followed by a fixing composition. In a “one-step” method, activation and fixing are combined using a single alkaline activator-fixing composition containing the fixing agent. None of the processing solutions include black-and-white developing agents. The photographic silver halide materials are preferably radiographic silver halide materials that have a reflective support and provide black-and-white images that can be viewed without a light box.

Photothermographic materials are coated with thermally developable imaging layers on both sides of the support. Such materials can be arranged in association with one or more phosphor intensifying screens capable of providing emission at a predetermined wavelength in imaging assemblies. These imaging assemblies can be exposed to X-radiation and thereby form a latent image in the photothermographic material that can be heat developed and used for medical diagnosis. The support of the photothermographic materials contains a crossover control composition that absorbs radiation at the predetermined wavelength, for example within the range of 300 to 450 nm, and has limited absorption at higher wavelengths.

A reflective radiographic material (at least 200 system speed) is useful especially to provide images that can be viewed without a light box. This reflective radiographic material has a reflective support, a silver halide emulsion on one side of the support only, and a photographic speed of at least 200. The reflective material also includes an incorporated black-and-white developing agent and a co-developing agent, and can be used with a single fluorescent intensifying screen as part of an imaging assembly. The reflective support enables viewing the resulting image without a light box and the high speed of the material enables the use of low power X-radiation generating equipment. The incorporated black-and-white developing agent and co-developing agent allow the radiographic material to be quickly processed after exposure using simplified processing chemistry.
