Sources of Element 104: Element 104 has not been found in nature. It is only produced by nuclear bombardment or decay of heavier isotopes . In 1964, researchers at the Russian's facility at Dubna bombarded a plutonium-242 target with neon-22 ions to produce the isotope most likely rutherfordium-259.
