WebThe Carbon 14, or radiocarbon dating method is one of the best-known methods of dating human fossils, and has been around since the late 1940s. The Carbon 14 (C-14) dating method is a radiometric dating method. A radiometric dating uses the known rate of decay of radioactive isotopes to date an object. WebAnswer (1 of 7): The accuracy of Carbon 14 is limited by the ability to measure the quantity of C-14 and its half life. It is also limited by source C14 and sequestration limits on the dating. In order to date something you need to know the level of C14 when the item was sequestered, the rate of...
