He was experimenting with cathode rays when he discovered that a type of paper that shines under ultraviolet light and cathode rays also shone in his dark laboratory in the presence of a new material. Thus, he discovered a source of an as yet unknown radiation, which he named X-ray radiation. He soon discovered that the radiation passes differently through different structures and materials. Soon, physicians applied this radiation in diagnostics and as a form of therapy for cancer and tuberculosis patients. In 1901 Röntgen was the first person to win the new Nobel prize (in physics). He refrained from applying for a patent as a gift to society, and soon afterwards X-ray radiation found applications in many forms (e.g. in shoe shops, to check the correct position of the foot in the shoe).…
