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.
A gamma ray is electromagnetic radiation (similar to visible light, but at a much higher energy in the electromagnetic spectrum) given off by the nucleus of an atom as a means of releasing excess energy, and is oftentimes released when an atom undergoes decay by emitting an alpha or a beta particle.
