Gamma radiation is a very high-frequency
electromagnetic radiation, similar in nature
to X-rays but of shorter wavelength, emitted
by the nuclei of radioactive substances
during decay or by the interactions of
high-energy electrons with matter. Cosmic
gamma rays have been identified as coming
from pulsars, radio galaxies, and quasars,
although they cannot penetrate the Earth's
atmosphere.
