Isotopos De Ferro
Le ferro natural (26Fe) ha quatro isotopos stabil: 5,845% de 54Fe (possibilemente radioactive con un semivita de plus que 4,4×1020 annos), 91,754% de 56Fe, 2,119% de 57Fe, e 0,286% de 58Fe.
On cognosce 24 isotopos radioactive, le plus stabil de illos es 60Fe (con un semivita de 2,6 milliones de annos) e 55Fe (con un semivita de 2,7 annos).
Un grande parte del laboro anterior pro mensurar le composition isotopic del Fe se ha concentrate in determinar le variationes de 60Fe causate per le processos que accompagna le nucleosynthesis (i.e., studios de meteorites) e le formation de mineralos. Tamen, durante le ultime decada, le progressos in le technologia de spectroscopia de massa ha permittite le detection e quantification de minusculas e natural variationes in le proportiones de le isotopos stabil del ferro. Un grande parte de iste laboro ha essite promovite per le communitates de scientias del Terra e planetari, ma il comencia a haber applicationes a systemas biologic e industrial.
