  • 3. • Various types of ionizing radiation may be produced by radioactive decay, nuclear fission and nuclear fusion, and by particle accelerators and naturally occurring cosmic rays. Examples:• Alpha Particles - are energetic, positively charged particles (helium nuclei) that rapidly lose energy when passing through matter.• Beta Particles - are fast moving, positively or negatively charged electrons emitted from the nucleus during radioactive decay.
  • 4. • Gamma Rays - Like visible light and x- rays, gamma rays are weightless packets of energy called photons.• X Rays - are high-energy photons produced by the interaction of charged particles with matter.
