Carbon 12 dating accuracy
They arrived at this conclusion by comparing age estimates obtained using two different methods - analysis of radioactive carbon in a sample and determination of the ratio of uranium to thorium in the sample.
In some cases, the latter ratio appears to be a much more accurate gauge of age than the customary method of carbon dating, the scientists said.
Atoms of carbon-12 have 6 neutrons, while atoms of carbon-14 contain 8 neutrons.
These skeptics do not provide scientific evidence for their views.The number given after the atom name (carbon) indicates the number of protons plus neutrons in an atom or ion.Atoms of both isotopes of carbon contain 6 protons.Each sample type has specific problems associated with its use for dating purposes, including contamination and special environmental effects.
