Abstract: Soft x-rays have been used in radiographing leather, textiles, paper, biological specimens, etc. The most recent application is in recording soft x-ray motion pictures directly upon the film, using a special emulsion having a high sensitivity to soft x-rays. Radiographs were made at a speed of 16 frames per second. The camera used was a Universal model C with the lens removed and a piece of infrared gelatin filter covering the gate to protect the film from light, and, at the same time, to furnish a support for the subject. The camera shutter absorbs the soft x-rays from the tube during the short exposures between frames, thus allowing continuous operation of the tube. A special form of x-ray tube fitted with an extremely thin window is required for the production of radiation suitable for radiographing thin subjects. Soft x-ray motion pictures of the yellow meal worm show peristaltic waves, gas bells leaving the stomach through the mouth, and the effects of various anesthetic vapors on the internal movements.
