This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.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. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.Libby received the Nobel Prize in Chemistry for his work in 1960.Plants and animals naturally incorporate both the abundant C-12 isotope and the much rarer radiocarbon isotope into their tissues in about the same proportions as the two occur in the atmosphere during their lifetimes.When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.

All carbon atoms have a nucleus containing six protons.

Carbon dating, or radiocarbon dating, can be helpful in determining the relative age of an object, but has many limitations.

The testing for carbon dating relies on many factors and should be used in conjunction with other methods of dating materials.

Sometimes, archaeologists will date an object by carbon dating another object nearby.

This method of dating obviously relies on assumptions about the relationship between the object and the actual tested material.
