A living thing takes in carbon-14 (along with stable carbon-12). As the carbon-14 decays, it is replaced with more carbon-14. After the organism dies, it stops taking in carbon. That includes carbon-14.

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. WebDec 7, 2016 · To radiocarbon date an organic material, a scientist can measure the ratio of remaining Carbon-14 to the unchanged Carbon-12 to see how long it has been since the material's source died. rcem homelessness
