Richard Foster Flint, a professor of geology at Yale University and an expert on the Pleistocene epoch, was among the first to apply radiocarbon dating to glacial events.
It is also called carbon and C dating. This technique is used to date the remains of organic materials. Dating samples are usually charcoal, wood, bone, or shell, but any tissue that was ever alive can be dated.

Jun 01, · Sometimes called carbon dating, this method works on organic material. Both plants and animals exchange carbon with their environment until they die. Afterward, the amount of the radioactive isotope carbon in their remains decreases. Measuring carbon in bones or a piece of wood provides an accurate date, but only within a limited range.
Carbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere, taking in carbon dioxide from the air for photosynthesis.. Cosmic ray protons blast nuclei in the upper atmosphere, producing neutrons which in turn bombard nitrogen, the major constituent of the atmosphere.
Animals and people eat plants and take in carbon as well. The ratio of normal carbon (carbon) to carbon in the air and in all living things at any given time is nearly constant.
