All carbon atoms have a nucleus containing six protons.

Ninety-nine percent of these also contain six neutrons.

It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.

In 1979, Desmond Clark said of the method “we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation” (3).

Radiocarbon dating may only be used on organic materials.

Typically (6): The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left.

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.

Willard Libby and his UChicago associates developed radiocarbon dating -- an innovative method to measure the age of organic materials.

Dedicated at the University of Chicago on October 10, 2016.

date of organic material - but an approximate age, usually within a range of a few years either way.
