In many fission reactions, researchers send a neutron toward a lighter isotope of uranium, uranium-235. The uranium absorbs the neutron, creating uranium-236. The uranium-236 then splits into two ...
radionuclides including the uranium isotope U-236, small amounts of transuranics (elements heavier than uranium, such as neptunium, plutonium and americium) and fission products such as technetium-99.
