The total mass of the isotope is indicated by the numerical superscript.

It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.As a result it is always undergoing natural radioactive decay while the abundances of the other isotopes are unchanged.Carbon-14 is most abundant in atmospheric carbon dioxide because it is constantly being produced by collisions between nitrogen atoms and cosmic rays at the upper limits of the atmosphere.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 the academic appointment above.Australian National University provides funding as a member of The Conversation AU.
