Miscellaneous Applications of Radiography and Fluoroscopy


X-ray inspection of industrial products and materials for gross defects has been in use quite extensively outside the fields of casting and welding. The two general methods by which the X-ray examination may be conducted are “radiography” and “fluoroscopy.” If the X-ray shadow image is impressed upon photographic film or paper, the process is called “radiography.” If the shadow image is observed by the eye on a chemical screen which gives off visible light when struck by X-rays, the process is called “fluoroscopy.”

The author discusses the general conditions for the application of one or the other of the above methods. A number of actual problems solved wholly or in part by X-rays are described. Some cases also are considered which indicate possible future industrial uses. While the nature of this subject prohibits the development of a clear outline, it has been found possible to group the examples roughly under seven main headings: (1) assemblies; (2) ceramics, concrete, mica, coal, and asbestos; (3) foods and tobacco; (4) plastics; (5) textiles, paper, and leather; (6) wood; and (7) miscellaneous.
