hat is carbon dating? - ANSWER The process of using the radioactive isotopes in carbon-14. All living things contain carbon-14. Carbon-14 decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food. Once the organism dies, however, it cannot absorb carbon-14. This means that the amount of the radiocarbon in its tissues steadily decreases.
