microradiography

[¦mī·krō‚rād·ē′äg·rə·fē]
(analytical chemistry)
Technique for the study of surfaces of solids by monochromatic-radiation (such as x-ray) contrast effects shown via projection or enlargement of a contact radiograph.
(graphic arts)
The radiography of small objects having details too fine to be seen by the unaided eye, with optical enlargement of the resulting negative.
