An Inside Look at X-rays

An Inside Look at X-rays

by Rismary Cabrera
When you think of it, modern diagnostic tools are quite remarkable. For most of human history no one could see what actually went on inside the human body. That all started to change in 1895 when a German professor of physics, Wilhelm Conrad Roentgen, made an accidental discovery while working with cathode-ray tubes. He happened to have some crystals on a nearby table and looked up to see them glowing as he worked on hazy afternoon. Long story short, he accidentally discovered a new kind of energy ray he dubbed X-rays. The very first human to have an X-ray was his wife. He took X-ray pictures of her hand.
