How do scientists use radiocarbon dating
WebApr 28, 2024 · The principle of dating revolves around carbon-14 (C-14), an isotope that loses half of its radioactivity (half-life) about every 5,730 years. Since C-14 is constantly being created in the atmosphere and incorporated into various life forms via the carbon cycle, one can expect the older a sample becomes, the less radiocarbon it has. WebJul 10, 2013 · Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50,000 years. Carbon is found in different forms in the environment – mainly in the stable form of carbon-12 and the unstable form of carbon-14.
