Energetic Quanta: X-rays & Gamma-Rays

Gamma rays and X-rays are types of photons…

  • That represent pure electromagnetic energy 
  • That progress at the speed of light
  • That may pass through all human tissues unimpeded and unchanged
  • Having no mass or charge, are neither attracted to nor repulsed by charged particles
  • Gamma-rays originate from the nucleus
  • X-rays originate from electron clouds
