Abstract:

The geological X-radiologist must combine four factors that govern radiographic film density to produce a readable radiograph. The relationship of these factors--kilovoltage, exposure conditions, kind of material, and thickness of material--to a desirable film density is shown by exposure guides, which permit the radiographer to select a suitable kilovoltage and exposure for a given sample. In this study guides were prepared for marine mud, sandstone, limestone, and shale. Author
