International Nuclear Safety Group International Nuclear Safety Group "This article is about the International Nuclear Safety Group. For other uses, see International Atomic Energy Agency." The International Nuclear Safety Group, formerly the International Nuclear Safety Advisory Group (INSAG), is an international organization that works to make nuclear safety clear and accessible for all. INSAG was created directly after the Chernobyl disaster on April 26, 1986. As part of the IAEA, the INSAG headquarters are located in Vienna. Under the direction of the International Atomic Energy Agency, INSAG helps to provide recommendations on nuclear safety approaches, emphasizing the importance of nuclear safety, advising establishments when
Uses of radioactivity in oil and gas wells high energy gamma rays. The attenuation of these gamma rays gives an accurate measure of formation density; this has been a standard oilfield tool since 1965. Another source is americium berylium (Am-Be) neutron source used in evaluation of the porosity of the formation, and this has been used since 1950. In a drilling context, these sources are used by trained personnel, and radiation exposure of those personnel is monitored. Usage is covered by licenses from International Atomic Energy Agency (IAEA) guidelines, SU or European Union protocols, and the Environment Agency in the UK. Licenses are required for access, transport, and
