Aug 31, 2018  · X rays are produced in a more energetic version of the same process. If you want to make X rays, you simply fire a beam of really high-energy electrons (accelerated using a high-voltage electricity supply) at a piece of metal (typically tungsten). What gets reflected back, in this case, is neither light nor electrons but a beam of X rays.

Characteristic x-rays are emitted from heavy elements when their electrons make transitions between the lower atomic energy levels. The characteristic x-ray emission which is shown as two sharp peaks in the illustration at left occur when vacancies are produced in the n=1 or K-shell of the atom and electrons drop down from above to fill the gap.

X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. The distinction between X-rays and gamma rays is not so simple and has changed in recent decades. According to the currently valid definition, X-rays are emitted by electrons outside the nucleus, while gamma rays are emitted by the nucleus.

In X-ray diagnostics, radiation that is partly transmitted through and partly absorbed in the irradiated object is utilised. An X-ray image shows the variations in transmission caused by structures in the object of varying thickness, density or atomic composition. In Figure 1, the necessary attributes for X-ray imaging are shown: X-ray source, object

Gamma ray. Gamma rays are also produced in the important process of pair annihilation, in which an electron and its antiparticle, a positron, vanish and two photons are created. The photons are emitted in opposite directions and must each carry 511 keV of energy—the rest mass energy ( see relativistic mass) of the electron and positron.
