X-ray X-ray radiation was first discovered by accident in 1895 by the German physicist Wilhelm Conrad Roentgen. The discovery earned Roentgen the very first Nobel Prize for Physics. X-rays are a type of high-energy electromagnetic radiation which produce images by passing through objects such as Sydney harbour fish onto photographic film. The dense parts of objects, such as bones, absorb the X-rays and appear as light regions on the film. Over one hundred years after the discovery of X-rays, biologists and archaeologists in museums all over the world still use this technology to examine the bone structure of specimens.
