Carbon 14 dating debate dating by voodoo
Radiocarbon dating estimates can be obtained on wood, charcoal, marine and freshwater shells, bone and antler, and peat and organic-bearing sediments.
They can also be obtained from carbonate deposits such as tufa, calcite, marl, dissolved carbon dioxide, and carbonates in ocean, lake and groundwater sources.

The word "estimates" is used because there is a significant amount of uncertainty in these measurements.
Libby, the discoverer of the C14 dating method, was very disappointed with this problem.
So I did a bit of research to fill in the gaps in my understanding, and not surprisingly I found the details to be quite interesting.Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes.When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.What did surprise me was the huge number of Web sites and books vigorously attacking the legitimacy of what I had thought was a fairly straightforward, uncontroversial test.Apparently carbon dating is right up there with evolution in terms of the disdain it evokes from certain religious groups.
Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.
