We gain benefits from this energy and we classify these energies into two main types:

  1. Non-ionizing radiation has enough energy to excite atoms, making them move more rapidly. Examples of non-ionizing sources include microwave ovens, radio transmissions, cell phones, and visible light.
  2. Ionizing radiation has enough energy to change atoms by removing electrons from them, a process called ionization. Examples of ionizing sources are X-rays, nuclear power
