![]() ![]() ![]() How is carbon-14 produced?Ĭosmic rays enter the earth's atmosphere in large numbers every day and when one collides with an atom in the atmosphere, it can create a secondary cosmic ray in the form of an energetic neutron. Age determinations can also be obtained from carbonate deposits such as calcite, dissolved carbon dioxide, and carbonates in ocean, lake, and groundwater sources. Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments. Libby and coworkers, and it has provided a way to determine the ages of different materials in archeology, geology, geophysics, and other branches of science. It was developed right after World War II by Willard F. Radiocarbon dating is a method of estimating the age of organic material. In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works. ![]() Explain how carbon can help determine the age of some objects.Īs 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.Describe why carbon can be found in all living organisms.After reading this section you will be able to do the following: ![]()
