Most carbon atoms have six protons and six neutrons in their nuclei and are called carbon Carbon 12 is very stable. But a tiny percentage of carbon is made of carbon 14, or radiocarbon, which has six protons and eight neutrons and is not stable: Carbon 14 is continually being created in the Earth's atmosphere by the interaction of nitrogen and gamma rays from outer space.
Since atmospheric carbon 14 arises at about the same rate that the atom decays, the Earth's levels of carbon 14 have remained constant. In living organisms, which are always taking in carbon, the levels of carbon 14 likewise stay constant. But in a dead organism, no new carbon is coming in, and its carbon 14 gradually begins to decay. So by measuring carbon 14 levels in an organism that died long ago, researchers can figure out when it died.
The procedure of radiocarbon dating can be used for remains that are up to 50, years old. Radiometric dating based on the decay of the isotope carbon It is used to date organic materials less than 70, years old.
