Radioactive dating of fossils depends on the decay of Camfreewatch
Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.
This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Some do not change with time and form stable isotopes (i.e.
Except for gamma decay or internal conversion from a nuclear excited state, the decay is a nuclear transmutation resulting in a daughter containing a different number of protons or neutrons (or both).
When the number of protons changes, an atom of a different chemical element is created.
The half-lives of several radioactive isotopes are known and are used often to figure out the age of newly found fossils.
