DO You Know?

•    X-rays were discovered by accident when German scientist Wilhelm Conrad Roentgen (27 March 1845–10 February 1923) was experimenting with vacuum tubes in 1895.
•    Wilhelm Roentgen, the scientist who discovered X-rays, was awarded the very first Nobel Prize in Physics in 1901. He refused to take patents related to his discovery because he wanted humankind as a whole to benefit.
•    X-radiation or X-ray is a form of high-energy electromagnetic radiation.

Other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, visible light, ultraviolet light, and gamma rays. They all travel in waves, but have different wavelengths.
•    From identifying broken bones to disease, the X-ray is one of the most useful medical advancements in history. It is also the oldest and most common form of imaging.
•    X-rays can be divided into hard X-rays and soft X-rays. Because hard X-rays have higher energy and, therefore, higher penetrative ability, they are used in medical radiography and airport security.
•    The first X-ray (or roentgenogram) was of Roentgen’s wife’s hand, complete with wedding ring, in 1895. His wife was less than impressed and declared: “I have seen my death!”
•    The term “X-ray” is used to refer to both the image itself and to the method.
•    X-rays have enough energy to ionize atoms and disrupt molecular bonds, which makes them harmful to living tissue.
•    Wilhelm Conrad Roentgen was mystified by the radiation he had discovered when he discovered X-rays, so he temporarily called them “X-rays,” with the “x” being a mathematical symbol for something unknown.
