The field of radiocarbon dating has become a technical one far removed from the naive simplicity which characterized its initial introduction by Libby in the late 's. It is, therefore, not surprising that many misconceptions about what radiocarbon can or cannot do and what it has or has not shown are prevalent among creationists and evolutionists - lay people as well as scientists not.
Jan 06, · Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, and the many people in the general public have at least heard of it. But there are many misconceptions about how radiocarbon works and how reliable a technique it is.
The introduction of radiocarbon dating had an enormous influence on both archaeology and geology—an impact often referred to as the “radiocarbon revolution.” Before Libby’s research, investigators in these fields had to rely on methods of dating that were merely relative, such as comparing the layers of a site in which artifacts were found, presuming that the layers of a site were .

Radiocarbon dating doesn't work well on objects much older than twenty thousand years, because such objects have so little C left that their beta radiation is swamped out by the background radiation of cosmic rays and potassium (K) decay.
Tree-ring dating (see Topic 27) gives us a wonderful check on the radiocarbon dating method for the last years. That is, we can use carbon dating on a given tree-ring (the year sequence having been assembled from the overlapping tree-ring patterns of living and dead trees) and compare the resulting age with the tree-ring date.
Apr 30, · The age assignment for certain Viking bones caused a decades-long controversy until the carbon methodology used to date them was recently exposed for its flawed assumptions. 1 This case demonstrates that one-size-fits-all radiocarbon dating doesn’t work. This case demonstrates that one-size-fits-all radiocarbon dating doesn’t work.
Jun 06, · That may not seem like a huge deal, but in situations where a decade or two of discrepancy counts, radiocarbon dating could be misrepresenting important details. The science behind the dating method is fairly straightforward: nitrogen atoms in the atmosphere hit with cosmic radiation are converted into a type of carbon with eight neutrons.
May 31, · It remains to be seen which side of the controversy will “win” with revised radiocarbon dates that include the new offset. More significant, perhaps, is the recognition of a new factor that had not been considered in previous uses of radiocarbon dating. Here we see an “unknown unknown” coming to light that changes things.

Carbon dating is controversial for a couple of reasons. First of all, it's predicated upon a set of questionable assumptions. We have to assume, for example, that the rate of decay (that is, a 5, year half-life) has remained constant throughout the unobservable past.
Aug 25, · From Wikipedia, the free encyclopedia (Redirected from Radiocarbon 14 dating of the Shroud of Turin) The Shroud of Turin, a linen cloth that tradition associates with the crucifixion and burial of Jesus, has undergone numerous scientific tests, the most notable of which is radiocarbon dating, in an attempt to determine the relic 's authenticity.

Radiocarbon dating just helps us zero in on a more precise estimate. In the case of dinosaur fossils, Hugh Miller and his group of creationists claim to have obtained radiocarbon dates on endogenous sources of carbon But regarding the source of the radiocarbon signal detected, all they have are unverified claims. Nothing more.

Radiocarbon dating is science, and there is no controversy within science. Rather, there are people whose religious beliefs lead them to deny radiocarbon dating.

Radiocarbon (14 C) is a radioactive isotope of carbon that decays into 14 N by emitting beta [HOST]arbon forms in the atmosphere after cosmic rays knock neutrons off molecules of atmospheric gases. When 14 N in the air is exposed to such neutrons, a nucleus of 14 N captures one of the neutrons and emits a proton, thereby becoming 14 C. The 14 C is incorporated into atmospheric Author: Philip J.
