Gamma radiation is released from many of the radioisotopes found in the natural radiation decay series of uranium, thorium and actinium as well as being emitted by the naturally occurring radioisotopes potassium-40 and carbon-14. These are found in all rocks and soil and even in our food and water.

Most radioactive sources produce gamma rays, which are of various energies and intensities. • A “typical” photo-neutron source might consist of an inner aluminum-encapsulated gamma-emitting core (e.g., 1 inch diameter) surrounded by an eighth of an inch of the neutron emitting target. Gamma-Neutron Sources 23 ggg • The overall shape of the source might be cylindrical or spherical. • In the case of an antimony-beryllium source, the Cascade of gamma Gamma radioactivity generally accompanies alpha or beta decay, as this example of cobalt 60 shows. The nucleus of Cobalt-60 (a radioisotope with a half-life of 5,271 years) decays by undergoing beta radioactivity and forms a stable nucleus of nickel 60 The transformation, accompanied by the emission of an electron and an antineutrino, results in an excited nickel 60 nucleus 999 times out of 1,000.

Radio Isotope (Gamma) Sources. Manmade radioactive sources are produced by introducing an extra neutron to atoms of the source material. As the material rids itself of the neutron, energy is released in the form of gamma rays. Three of the more common industrial gamma-ray sources for industrial radiography are iridium-192, selenium-75 and cobalt-60.

Because both radium and radon are very The gamma function can also be used to calculate "volume" and "area" of n-dimensional hyperspheres. Calculating products [ edit ] The gamma function's ability to generalize factorial products immediately leads to applications in many areas of mathematics; in combinatorics , and by extension in areas such as probability theory and the Radio Isotope (Gamma) Sources.
