There's a small amount of radioactive carbon-14 in all living organisms. When they die no new carbon-14 is taken in by the dead organism. The carbon-14 it contained at the time of death decays over a long period of time. By measuring the amount of carbon-14 left in dead organic material the approximate time since it died can be worked out.

Radiocarbon dating uses carbon isotopes. Radiocarbon dating relies on the carbon isotopes carbon-14 and carbon-12. Scientists are looking for the ratio of those two isotopes in a sample. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.

Carbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere, taking in carbon dioxide from the air for photosynthesis.
