“Engineering X-Ray Inspection” is a circa 1940 United States Office of Education training film was produced by U.S. Office of Education and the Federal Security Agency. The film opens with a disconcerting hum and the camera peers at a massive x-ray machine (mark 00:30) in the “radiographic room” of an industrial x-ray inspection laboratory. We watch as a technician x-rays a steel gear to determine whether the casting is free of defects as the narrator explains the process. At mark 01:45 we see a casting that is full of defects as the narrator points to the differences and explains how potentially serious trouble was avoided as a result. With a general understanding of the use and importance of x-ray technology, the film goes on to provide a detailed, animated explanation of the generation of x-rays beginning at mark 02:22. The process is detailed for several minutes, with the narrator reminding the viewer at mark 09:13 that “x-radiation” is dangerous to living tissue and operators need to be outside of the room when operating the machine. Starting near mark 09:30 we’re reminded of the four major factors to remember when making a radiograph: the tube current, the voltage across the tube, the focus-film distance, and the exposure time. The film continues as we watch an operator carefully develop x-ray film and we run through additional procedures to meet the factors that had been introduced, and at mark 18:23 we see images of more faults in an x-rayed gear. As the film comes to a close the narrator reminds the viewer that skill and study are necessary to become an x-ray technician, but that the skill plays an invaluable role in production control.
