Low Voltage Radiographic and Micoradiographic Techniques for Graphite


Low-voltage radiography was studied to provide optimum techniques for graphite thickness less than 2 in. Significant improvements were made in image quality and sensitivity by use of an intermediate atmosphere of helium, bare film, and a thin beryllium-window X-ray tube. Use of a high resolution photographic emulsion allows contact microradiography to be performed on miniature specimens with a resolution of one micron.
