Gamma radiation
scroll
Highly-energetic, short-wave electromagnetic radiation
emitted from the nucleus of an atom. Gamma radiation energies usually
range between 0.01 and 10 MeV. X-rays also occur within this energy
range; they originate, however, not from the nucleus, but are generated
by electron transfers in the electron sheath or by electron deceleration
in matter (bremsstrahlung). In general, alpha and beta decays and always
the fission process are accompanied by gamma radiation. Gamma rays are
extremely penetrative and may best be weakened by material of high density
(lead) and high atomic number.
