Gamma ray (also called gamma radiation), denoted by the lower-case Greek letter gamma (Î³ or Î³ {\displaystyle \gamma } ), is penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei and consists of high-energy photons.
Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.These waves are generated by radioactive atoms and in nuclear explosions.Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells. Gamma-rays travel to us across vast distances of the universe, only to be absorbed by the Earth's atmosphere.hese waves are generated by radioactive atoms and in nuclear explosions.
