What are some common sources of gamma radiation? 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. Gamma-rays are the highest-energy form of light in the universe. Some are generated by transient events, such as solar flares and the huge star explosions known as supernovas. Others are produced Sources of Radiation. Gamma rays are the photons emitted from the atomic nuclear decay of radioactive isotopes—for example, 137 Cs (cesium) or 60 Co (cobalt).

Lunsford introduced the first clinical 201-source Gamma Knife unit to North America (the fifth gamma unit worldwide). 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.

Analytics’ Mixed Gamma Standard utilizes the basic eight radionuclides listed as Option 1 in the Mixed Gamma-Ray Standards Table. The approximate gamma-ray emission rate for a 3 microCi (111 kBq) source is given as an example. Option 2 adds 241Am to the mixture to extend the energy range down to 59.5 keV.

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. source as a point source, if the distance from the source is more than twice its maximum dimension.
Other things that gamma rays can detect are: Weld defect, density change, and non-uniformity of the material. In astronomy, to look for distant gamma-ray sources.
