Carbon dating age determination

Though still heavily used, relative dating is now augmented by several modern dating techniques.Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.

There are well-known methods of finding the ages of some natural objects.Over time, carbon-14 decays radioactively and turns into nitrogen.A living organism takes in both carbon-12 and carbon-14 from the environment in the same relative proportion that they existed naturally.After the second half-life has elapsed, yet another 50% of the remaining parent isotope will decay into daughter isotopes, and so on.For all practical purposes, the original isotope is considered extinct after 6 half-life intervals. A small portion of a meteorite is vaporized in the device forming ions.
