| microradiography | Production of a radiographic image of a small or very thin object on fine-grained photographic film under conditions which permit subsequent microscopic examination or enlargement of the radiograph at linear magnifications of up to several hundred and with a resolution approaching the resolving power of the photographic emulsion (about 1000 lines per millimeter).

| microradiography, contact | <microscopy> A method of making micrographs by means of X-rays. The specimen is placed close to a fine-grained photographic emulsion at some distance from the X-ray source. The X rays pass through the specimen and the differential absorption and the scattering of the radiation is recorded by the emulsion. The resulting negative is examined and photographed through a light microscope. (05 Aug 1998) |
