X Rays

By: Brianna Lee


A relatively high-energy photon with wavelength in the approximate range from 0.01 to 10 nano meters corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10^16Hz to 3×10 ^19Hz) and energies in the range 100 eV to 100 keV . They are shorter in wavelength than UV rays and longer than gamma rays

Medical x ray machines

  • X rays and also gamma rays are used in radiation therapy to kill diseased cells
  • X-rays can easily penetrate low-density material, such as flesh. They are reflected or absorbed, however, by high-density material such as bone. The picture made by an X-ray machine shows the denser materials (like bones) as dark areas.

Benefits & Advantages

  • fast — the results of X-rays are often available the same day, in simple cases even within the hour
  • are painless and non-invasive
  • don’t require any special preparation (except when contrast media is used)
  • require no recovery time — you can go straight back to work or school after an X-ray is finished.


  • If a woman is pregnant they have to notify the doctor and tell them so the can take special measure so the baby isn't harmed in any kind of way
  • Radiation can cause cell damage
  • cancer if exposed to a lot of radiation
