    Title: X-Rays and Gamma Rays
    Type: Text Slide
    • X-rays are photons (electromagnetic radiations) emitted from electron orbits, such as when an excited orbital electron "falls" back to a lower energy orbit.
    • Gamma rays are photons emitted from the nucleus, often as part of radioactive decay.
