... Radiocarbon dating is the process of determining the age of an object by measuring the amount of carbon-14 remaining in that object. Carbon’s isotopes include carbon-12 and carbon14. When an organism is alive, the ratio of carbon- 14 atoms to carbon-12 atoms in the organism remains nearly constant. ...
