About this Program

This program will provide a review of the history and discovery of x-rays. A comparison of the various types of electromagnetic radiation will be made, as well as correlation of wavelength and intensity. An observation will be made between environmental radiation, and medical radiation, exposures for those in the United States. The effect of x-rays on an atom will be covered, and the basic components of the x-ray tube will be examined. 



What Are X-rays:

History of x-rays       

  • Roentgen
  • Clarence Dally

Properties of Ionizing Radiation

  • Photon Energy
  • Electromagnetic Spectrum

X-ray Interaction and Attenuation

X-ray Production


How it Works:

  • Your On Demand CE activity that you purchased will be located in your “My Account” section once you log into the MTMI Website.
  • You have three attempts to pass each quiz.
  • You must earn a score of 75 % or higher.
