Abstract: Drees, L.R. and Wilding, L.P., 1983. Microradiography as a submicroscopic tool. Geoderma, 30: 65-76. Contact X-ray microradiography is a microscopic application of conventional radiography. The resulting in situ shadow images on fine-grained photographic film can be viewed under the light microscope up to 500X without loss of detail or depth of focus distortions. Differential absorbance of X-rays by the sample offers a non-destructive means of examining the internal phases of a specimen which may be obscured in light transmission or SEM microscopy. Such phases include voids, nodules, concretions, occluded minerals, lithorelicts, and other chemical segregations. Microradiography is an especially convenient tool because of minimum sample preparation and the small investment cost for camera fabrication to existing X-ray equipment. © 1983.
