Ever and anon living thing on earth contains the element carbon. When an organism dies, be it a plant or an animal, the carbon acquired during its existence begins to decay at a steady, predictable rate, releasing carbon, a radioactive isotope with a half-life of 5, years. By means of measuring the amount of carbon left in the organism, scientists can estimate how long in the past the organism died. Radiocarbon dates are often reported as a range. In recent years, scientists have refined methods for radiocarbon dating.

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. This neutron bombardment produces the radioactive isotope carbon

Crave Radiocarbon dating reflections Three isotopes of carbon are found in nature; carbon, carbon and carbon Hereafter these isotopes will be referred to as 12C, 13C, and 14C. The half-life is the time taken for an amount of a radioactive isotope to decay to half its original value. A unique characteristic of 14C is that it is constantly formed in the atmosphere. Photosynthesis incorporates 14C into plants and therefore animals that eat the plants.
