Simply Science.

The unstable or more commonly known radioactive isotopes break down by radioactive decay into other isotopes.

Potassium—argon dating.

An unstable isotope spontaneously emits radiation from its atomic nucleus.

The amount of carbon isotopes within living organisms reaches an equilibrium value, on death no more is taken up, and the 14C present starts to decay at a known rate.
