An example of radiocarbon dating

One of the nice things about this method is that we don't have to worry about carbon being lost from the sample.Because we are measuring the abundance of two isotopes of carbon, and because isotopes of the same element will be chemically identical, no ordinary process can preferentially remove C is going to be small enough to begin with, being only 0.0000000001% of atmospheric carbon, and then as the decay process progresses it's going to get smaller and smaller.

For this reason radiocarbon dating is of more interest to archaeologists than to geologists. From this science, we are able to approximate the date at which the organism were living on Earth.Radiocarbon dating is used in many fields to learn information about the past conditions of organisms and the environments present on Earth.However, most of the finds from the ice cannot be dated by typology.They are artefacts in organic materials and often unique – not found anywhere else. In the 1940ies, the American scientist Willard Libby developed a method for dating organic materials, so-called radiocarbon dating.Once an organism is decoupled from these cycles (i.e., death), then the carbon-14 decays until essentially gone.
