WebSep 14, 2024 · Carbon dating works on the principle of the decay constant. In an organic substance, carbon-14 stops changing after death. The difference in the concentration of carbon-14 in the atmosphere and the dead organism is calculated to determine its age. How accurate is carbon-14 dating? WebCarbon dating is based upon the decay of 14 C, a radioactive isotope of carbon with a relatively long half-life (5700 years). While 12 C is the most abundant carbon isotope, there is a close to constant ratio of 12 C to 14 C in the environment, and hence in the molecules, cells, and tissues of living organisms.
