Is carbon dating accuracy or not
Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.
Radiocarbon samples which obtain their carbon from a different source (or reservoir) than atmospheric carbon may yield what is termed apparent ages.
A shellfish alive today in a lake within a limestone catchment, for instance, will yield a radiocarbon date which is excessively old.
The thermoluminescence technique is the only physical means of determining the absolute age of pottery presently available.

In a related article on geologic ages (Ages), we presented a chart with the various geologic eras and their ages.
In a separate article (Radiometric dating), we sketched in some technical detail how these dates are calculated using radiometric dating techniques.
Implicit in the Conventional Radiocarbon Age BP is the fact that it is not adjusted for this correction.
In this page, we consider natural reservoir variations and variations brought about by human interaction].
The lake, in this case, has a different radiocarbon reservoir than that of the majority of the radiocarbon in the biosphere and therefore an accurate radiocarbon age requires that a correction be made to account for it.
The age of the pottery, in principle, may then be determined by the relation Age = Accumulated dose / Dose per year Although conceptually straightforward, TL has proven to to be far from simple in practice.
When pottery is fired, it loses all its previously acquired TL, and on cooling the TL begins again to build up.
