It is an essential technology that is heavily involved in archaeology and should be explored in greater depth. Radiocarbon dating uses the naturally occurring isotope Carbon to approximate the age of organic materials. Often, archaeologists use graves and plant remains to date sites. Since its conception by Willard Libby in , it has been invaluable to the discipline. In fact, many important archaeological artifacts have been dated using this method including some of the Dead Sea Scrolls and the Shroud of Turin. Though radiocarbon dating is startlingly accurate for the most part, it has a few sizable flaws.
This article will explain how carbon dating is supposed to work and then show you the serious flaws with this process. It is derived from a transcript of Dr. His videos and materials are not copyrighted.
Since , scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain. New research shows, however, that some estimates based on carbon may have erred by thousands of years. It is too soon to know whether the discovery will seriously upset the estimated dates of events like the arrival of human beings in the Western Hemisphere, scientists said. But it is already clear that the carbon method of dating will have to be recalibrated and corrected in some cases. 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.
