In 1895, the German physicist, Wilhelm Roentgen was studying the fluorescence produced by cathode rays(electrons) when he discovered a form of highly penetrating radiation which he termed "x-rays". Through subsequent experiments, he and other researchers demonstrated that these x-rays possessed the ability to penetrate matter differentially, as a function of density and elemental composition. This led promptly to the widespread application of x-rays for observing the internal structure of various objects, including the human body.
