Because atmospheric carbon 14 arises at about the same rate that the atom decays, Earth's levels of carbon 14 have remained fairly constant.

Once an organism is dead, however, no new carbon is actively absorbed by its tissues, and its carbon 14 gradually decays.

A very small percentage of carbon, however, consists of the isotope carbon 14, or radiocarbon, which is unstable.
