Principle of X-ray

Overview of X-Ray



November 8, 1895, WC ROENCGEN confirmed that fluorescence was caused by unknown rays during an experiment using a closed-off cathode tube, He named it X-rays, and published a paper on December 8, 1895, which granted him the 1st Nobel Prize in Physics.

Actions of X-Ray

  • Physical Reaction
    : Excitement, ionization, exothermic and fluorescent reaction
  • Chemical Reaction
    : When ionization or excitation is generated due to the high-speed electrons made by X-rays, chemical changes may occur.
  • Physical, Chemical Reaction
    : Like visible light, X-rays have a photographic effect on photosensitizers. Accordingly, X-ray generates the internal structure of the human body on the film image and used for dose measurement with its chromatic effect.
  • Biological Reaction
    : In addition to acute effects such as skin erythema and ulceration, x-rays have a latent effect that is expressed after a long incubation period, so it can cause aging and genetic disorders. Moreover, X-ray is used for radiation treatment of malignant tumors.
