X-ray fluorescence is the emission of characteristic secondary X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science, archaeology and art objects such as paintings and murals.
Teeth and Bones â A History of X-Rays An x-ray is a form of electromagnetic radiation and can produce an image of somethings internal composition, especially parts of the body. Today, x-rays are often used in hospitals and other medical facilities in helping to diagnose broken bones and other issues. X-rays were initially discovered in the late 1800s by a German physicist. This discovery led to many advances in the field of radiology, especially in regards to medical use of x-rays. In 1895, Wilhelm Rontgen, a German physicist, was the first person to discover and systematically study x-rays.
