Initially, if halite (common salt) is exposed to gamma radiation, it turns amber because of f-centers. They are mostly electrons trapped at sites of missing Cl- ions. In time the electrons migrate to Na+ ions and reduce it to Na metal. Atoms of Na metal, in turn, migrate to form colloidal sized aggregrates of sodium metal.Web
