Captured by nitrogen nuclei (N-14), neutrons transform these nuclei into carbon-14 (B).The carbon-14 atoms combine with the oxygen in the air to form carbon dioxide (C).Finally, CO2 molecules with radiocarbon, absorbed by vegetation, enter natural environment (D).IN2P3 Incoming cosmic rays create atoms of carbon 14 by colliding with nuclei in the upper atmosphere, liberating neutrons.This is why carbon 14, along with potassium 40, accounts for almost all the natural radioactivity of our body.When a living organism dies, the radioactive carbon is no longer absorbed, and the ratio of carbon 14 present begins to decrease.

The carbon 14 found in nature is constantly being regenerated by cosmic rays hitting the atmosphere.

Carbon dating is one type of radiometric dating, there are others.

Carbon dating uses the carbon-14 isotope, with a half life of about 5700 years.

Carbon-14 dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50,000 years old.

It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.
