Uranium-236 (U-236) is a radioactive isotope of uranium. It is one of the isotopes that can be produced through the capture of neutrons by uranium-235 (U-235), which is a more abundant isotope commonly used in nuclear reactors and weapons. U-236 has a relatively low occurrence in nature and is generally the result of nuclear reactions, such as those that occur in nuclear reactors or during the detonation of nuclear weapons.
