The\u00a0X-rays<\/b>\u00a0are electromagnetic radiation, not visible to the human eye, which is able to pass through opaque bodies and to print photographic films. The great application for which X-rays are known is the X-rays of our bones that we can obtain with them. In addition, X-rays are used in a number of other applications, which you can see below.<\/p>\n

ORIGIN OF X-RAYS. DISCOVERY<\/h2>\n

The X-rays<\/strong> are sometimes also known as R\u00f6ntgen rays<\/strong>. R\u00f6ntgen discovered X-rays in 1895 while experimenting with fluorescence. The moment when X-rays were discovered was a very important moment in science. It coincided with the discovery of radium by the Curies and the radioactivity<\/a> by Becquerel. They were all colleagues and each milestone was closely linked to the other.<\/p>\n

WHERE X-RAYS COME FROM. HOW TO GENERATE THEM<\/h2>\n

The X-rays<\/strong> are produced inside a glass tube, in which a high vacuum has been built up, and\u00a0<\/span>where a potential difference of approximately 50 to 150 KV is applied between their\u00a0<\/span>positive and negative poles. The cathode is heated and electrons are emitted by the thermionic effect. These electrons travel through the empty tube until they reach the anode, where collisions occur. <\/span><\/p>\n

Some of these collisions cause the promotion of some cortical electrons to higher layers, which upon falling back to their initial orbits emit EM energy, characteristic X-rays, whose frequency and energy (E=hv) are determined by the anode material.\u00a0<\/span><\/p>\n
