All radioactive dating is based on the fact that a radioactive substance, through its characteristic disintegration, eventually transmutes into a stable nuclide.
This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay. Note that pure U3O8 is black. See all other plans.
