A hydrocarbon found in beach sediments, for example, might derive from an oil spill or from waxes produced by plants.Rachel Wood does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment.

Animals and people take in carbon-14 by eating the plants.When isotopes are to be designated specifically, the chemical symbol is expanded to identify the mass (for example, C is not stable.As a result it is always undergoing natural radioactive decay while the abundances of the other isotopes are unchanged.The 6 proton 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons.They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.

Both Carbon-12 and Carbon-13 are stable, but Carbon-14 decays by very weak beta decay to nitrogen-14 with a half-life of approximately 5,730 years.
