Dating Methods using Radioactive Isotopes Oliver Seely Radiocarbon method The age of ancient artifacts which contain carbon can be determined by a method known as radiocarbon dating. This method is sometimes called C-14 or carbon-14 dating. Carbon-14 is formed in the upper atmosphere by the bombardment of nitrogen-14 by cosmic rays. Cosmic rays are protons, particles and some heavier ions.
carbon 14 has a half life of 5730 years how long does it takeAfter reading this section you will be able to do the following. Describe why carbon can be found in all living organisms. Explain how carbon can help determine the age of some objects. As you learned in the previous page, carbon dating uses the half-life of Carbon-14 to find the approximate age of certain objects that are 40,000 years old or younger.

It is also defined as the time taken for half the quantity of a radioactive how is the half life of carbon 14 used for dating archaeological samples in a sample to decay and form a stable element.
