<P> There was immediate interest from researchers for the X-ray . A.A. Campbell - Swinton and Nikola Tesla were amongst the firsts to test the new discovery . In 1896 , Thomas Edison investigated materials ' ability to fluoresce when exposed to X-rays , and found that calcium tungstate was the most effective substance . Around March 1896 , the fluoroscope he developed became the standard for medical X-ray examinations . Nevertheless , Edison dropped X-ray research around 1903 , even before the death of Clarence Madison Dally , one of his glassblowers . Dally had a habit of testing X-ray tubes on his hands , and acquired a cancer in them so tenacious that both arms were amputated in a futile attempt to save his life . </P>
