Radiometric dating school
Scientists know the half-life of C-14 (5,730 years), so they can figure out how long ago the organism died.
The primary carbon-containing compound in the atmosphere is carbon dioxide, and a very small amount of carbon dioxide contains C-14.
Welcome to the K12 section of the Radiocarbon WEBinfo site.
The aim here is to provide clear, understandable information relating to radiocarbon dating for the benefit of K12 students, as well as lay people who are not requiring detailed information about the method of radiocarbon dating itself.
Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay.
A useful application of half-lives is radioactive dating.
They used pottery and other materials in sites to date 'relatively'.
