  • Resuming the studies of crookes
  • Wilhem  Röntgen . Germany scientist and professor in physics.
  • X-ray of his wife
  •  Before the discovery of the X-rays an invention worked by Willian Crookes about electricity in tubes was essential for X-rays of Röntgen.
  • NEWS!
  • After covering the tube with a black cardboard to eliminate visible light, he observed a faint green glow from a screen with a layer of platinum-barium cyanide, which disappeared when the tube was turned off. He determined that the rays created a very penetrating, but invisible, radiation that went through great thicknesses of paper.
  • NOW...
  • He made the first human radiography, using his wife's hand. He called them "incognito rays", or "X-rays" because he did not know what they were, only that they were generated by cathode rays when hitting certain materials.
  • The news of the discovery of X-rays spread very quickly in the world.
  • The X-Rays its a great   tool to detect  diseases.
