➧Roentgen working with cathode ray tube in his laboratory, Roentgen observed crystal near a high voltage cathode ray tube exhibiting a fluorescent glow, ever when he shielded them with dark paper. some form of energy was being produced by the tube and it was penetrating the paper and causing the crystals to glow.
➧Roentgen placed various objects between the tube and the screen, and the screen still glowed. finally, he put his hand in front of the tube, and saw the outline of his bones projected into the fluorescent screen. Immediately after discovering x-rays themselves, he had discovered their most beneficial application.

➧Roentgen first publication about his discovery was released in the days that followed on 28 December 1895 it was entitled “On a new kind of rays”.
➧He suggested the name “X-ray” for his discovery, arguing that since the origin of the rays was unknown, it was appropriate to refer to them as X, the mathematical term for the unknown.
➧For the discovery, Roentgen was awarded the first noble prize in physics, in 1901 (During world war) x-ray were already being used for medical purposes.
