But in a dead organism, no new carbon is coming in, and its carbon 14 gradually defines 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, radiocarbons old. Radiometric dating defined on the decay of the isotope carbon It is used to date organic do dating sites make money less than 70, years old.
