Iron-60 is an iron isotope with a half-life of 2.6 million years, but was thought until 2009 to have a half-life of 1.5 million years. It undergoes beta decay to cobalt-60, which then decays with a half-life of about 5 years to stable nickel-60. Traces of iron-60 have been found in lunar samples. In phases of the meteorites … See more Naturally occurring iron (26Fe) consists of four stable isotopes: 5.845% of Fe (possibly radioactive with a half-life over 4.4×10 years), 91.754% of Fe, 2.119% of Fe and 0.286% of Fe.
