Future Availability of X-ray Film
JAMA: The Journal of the American Medical Association, 1965Silver, as silver halide, is basic to the photographic process. It is required in x-ray film and is thus indispensable to modern medicine. In 1964 free-world consumption of silver for coins and industry was about 550 million troy ounces. New mine production was about 215 million troy ounces.1The deficit was supplied primarily by shrinking US ...

Photographic Naming of X-ray Films
The British Journal of Radiology, 1949A photographic method of naming X-ray films, using a charging condenser relay circuit to give constant exposure time of illumination. A card bearing patient's particulars is interposed between the illumination and the film. Modification of cassettes is required by the insertion of a lead plate to protect the naming area of the film from radiation.

Characteristics of X-Ray Films and Screens
Radiology, 1947Most roentgenologists have long recognized the need of reliable quantitative data giving the speed, detail, and contrast characteristics of commercially available roentgenographic films and intensifying screens. From such information, the choice of the most satisfactory films and screens for use in a roentgenographic department may be greatly ...

The Use of X-ray Films in Beam Direction for X-ray Therapy
The British Journal of Radiology, 1949A method of Beam Direction by taking radiographs with the therapy tube under identical treatment conditions, using 190kV Kodirex or Ilfex type of film, 6½ in. × 4¾ in. The Industrial type of lead screens have been used for the thicker and more bony areas. The front screen is 0·004 in., and the back screen is 0·006 in. thick.

The Use of Photographic and X-Ray Films for X-Ray Measurements
Advances in X-ray Analysis, 1974AbstractExperiments were conducted on two underground nuclear tests with the primary objective of determining if high-intensity x-ray exposures can cause a failure of the photographic reciprocity law. The results of the experiments, which included exposures at intensities up to 1020 photons/cm2-sec, were in good agreement with standard diagnostic ...
