Carbon Dating & Archaeology | CyArk

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