What is carbon 14 dating used for
All living things have carbon in them; but a small amount of that carbon is radioactive. The law of conservation and mass states that matter can not be destroyed nor created.So that is why carbon-14 is used for radioactive dating. It decays to Nitrogen 14 and has a half life of 5,730 years.
The half-life in some of these isotopes is measured in millions or billions of years.carbon 14 ----------------------------------- No, NOT Carbon 14, Carbon 14 dating CAN ONLY BE USED is living (or once living) things.The Atoms used for radiometric dating of NON LIVING things are: Potassium/Argon Uranium/Lead Carbon 14 dating is the best known example of radiometric dating, but there are many others.The carbon-14 atoms that cosmic rays create combine with oxygen to form carbon dioxide, which plants absorb naturally and incorporate into plant fibers by photosynthesis.
Animals and people eat plants and take in carbon-14 as well.Carbon-14 is radioactive, with a half-life of about 5,700 years.
