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.
Gamma Rays. Gamma radiation from nuclear decay is a form of electromagnetic energy, as visible light, radio waves and X-rays are. They have very high energy compared to other types of radiation, and they have more penetrating power than X-rays; typically, lead, steel or thick concrete shielding is needed to block them.
