What is carbon 14 dating used for
- Potassium-Argon method – Potassium-40 decays to argon and calcium.
- Uranium-Lead method - Rubidium-Strontium method - Carbon-14 method – also known as carbon dating.
The carbon-14 atoms are always decaying, but they are being replaced by new carbon-14 atoms at a constant rate.
At this moment, your body has a certain percentage of carbon-14 atoms in it, and all living plants and animals have the same percentage.
It is not uncommon for a cosmic ray to collide with an atom in the atmosphere, creating a secondary cosmic ray in the form of an energetic neutron, and for these energetic neutrons to collide with nitrogen atoms.
When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).
Carbon 14 is used for fossils of fairly recent origin, as it becomes less and less accurate beyond 10 half lives (about 50 thousand years). Longer lived isotopes such as uranium/uranium, uranium/thorium, and potassium/argon are used to date inorganic materials of volcanic origin, such as rock or layers of volcanic ash, and can yield results ranging…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 ratio of normal carbon (carbon-12) to carbon-14 in the air and in all living things at any given time is nearly constant.Maybe one in a trillion carbon atoms are carbon-14.
