Gamma rays are the most energetic type of light, packing a punch strong enough to pierce through metal or concrete barriers. More energetic than X-rays, they are born in the chaos of exploding stars, the annihilation of electrons and the decay of radioactive atoms.
How are gamma rays used? Gamma rays are a form of electromagnetic radiation, and they have the greatest energy of all forms of electromagnetic radiation. Gamma rays can easily penetrate most materials, including lead. Gamma rays are classified as ionizing radiation and are therefore hazardous to living cells.
