For example, when lime absorbs CO2 it creates mortar, so the mortar can be dated via radiocarbon since some CO2 molecules are comprised of C14 (Bowman, 13).But in general, non-organic materials usually cannot be dated via radiocarbon.Many of these problems have been solved in recent years, but many have not.Response to Assumptions C14 production in the atmosphere is constant.As is common fact, plants photosynthesize and consume CO2, fixing its carbon.Since a small fraction of CO2 contains C14, some of carbon fixed within the plant is that of C14.Posted: February 18, 2013 in Biology Related, Essays and Papers, Fossil Related, geology related, History Related Tags: ancient, assumption, c14, carbon, carbon14, date, dating, dendrochronology, effect, history, isotope, method, radio, reservoir, rings, tree Radiocarbon dating is a popular dating method the general public is fairly familiar with.
-The biosphere has had the same overall concentration of C14. Taylor, professor of anthropology at University of California Los Angeles and University of California Riverside lists the following assumptions: -The concentration of C14 has been constant over the C14 timescale. -C14 concentration in the carbon dioxide cycle is constant. -C14 decay formation and decay rates are in equilibrium (Snelling, 856).
Yet, as simple and straightforward as this seems, the process of dating objects via radiocarbon is far from simple and straightforward.
Here I will present what radiocarbon is, the dating methods, the assumptions that govern them, and the known discrepancies that plague the method.
This is a common misunderstanding the general layman has of radiocarbon dating that is important to clarify.
What makes C14 significant is that it is an unstable atom.
