#3 X-Rays

Accident causer: Wilhelm Conrad Roentgen

In 1895, a German Physicist, Wilhelm.C. Roentgen was fooling around with radiation producing cathode-rays. During the experiment, he noticed that the fluorescent screen in his lab started to glow whenever he switched on the cathode rays. This was distracting the physicist and so he covered the screen with a cardboard to block out the rays from falling on the screen. However, the screen continued to glow. This grabbed his interest and he started placing  different objects between cathode ray tube and fluorescent screen without success. Finally Roentgen placed his own hand between the screen and the tube and was surprised to see a silhouette of his bones projected onto the screen. Through this accidental experiment, Roentgen had discovered X-rays and at the same time worked out that they would be beneficial in medical science.
