History of Radiography. X-rays were discovered in 1895 by Wilhelm Conrad Roentgen (1845-1923) who was a Professor at Wuerzburg University in Germany. Working with a cathode-ray tube in his laboratory, Roentgen observed a fluorescent glow of crystals on a table near his tube.
Other uses of X-rays. Before the use of gamma rays [gamma ray: A type of ionising radiation that consists of a high-energy electromagnetic wave.] , a high-energy, concentrated dose of X-rays was used to treat some cancers. X-rays are still used to identify tumours [tumour: An abnormal growth of cells, often caused by cancer.] . X-rays are also used in CAT scans.
