Line 9: prevented this from occurring. Ignorance of the harmful effects of x-rays resulted in the absence of standard radiation safety procedures which are employed today. Scientists and physicians would often place their hands directly in the x-ray beam resulting in [[radiation burns]]. Edison's assistant [[Clarence Madison Dally]] (1865-1904) died as a result of exposure to radiation from fluoroscopes, and in 1903, Edison abandoned his work on fluoroscopes, saying "Don't talk to me about X-rays, I am afraid of them."<ref>Duke University Rare Book, Manuscript, and Special Collections Library : "Edison Fears the Hidden Perils of the X-Rays", ''[[New York World]]'', August 3, 1903, Durham, NC.</ref>. Trivial uses for the technology also resulted, including the [[shoe-fitting fluoroscope]] used by shoe stores in the 1930s-1950s.[http://www.orau.org/ptp/collection/shoefittingfluor/shoe.htm] Due to the limited light produced from the fluorescent screens, early [[radiologists]] were required to sit in a darkened room, in which the procedure was to be performed, accustomizing their eyes to the dark and thereby increasing their sensitivity to the light. The placement of the radiologist behind the screen resulted in significant [[radiation dose]]s to the radiologist. [[Red adaptation goggles]] were developed by [[Wilhelm Trendelenburg]] in 1916 to address the problem of [[dark adaptation]] of the eyes, previously studied by [[Antoine Beclere]]. The resulting red light from the goggles' filtration correctly sensitized the physician's eyes prior to the procedure while still allowing him to receive enough light to function normally. Line 56: Another common procedure is the '''modified barium swallow study''' during which [[barium]]-impregnated liquids and solids are ingested by the patient. A radiologist records and, with a speech pathologist, interprets the resulting images to diagnose oral and pharyngeal swallowing dysfunction. Modified barium swallow studies are also used in studying normal swallow function. ==References== {{reflist}} ==See also==
