Can carbon dating be trusted

How reliable is radiocarbon dating?

Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods. This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen N into carbon C or radiocarbon. Living organisms are constantly incorporating this C into their bodies along with other carbon isotopes. When the organisms die, they stop incorporating new C, and the old C starts to decay back into N by emitting beta particles. The older an organism's remains are, the less beta radiation it emits because its C is steadily dwindling at a predictable rate. So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. C decays with a half-life of 5, years.

Dating is everything in archaeology. Exciting discoveries of ancient burial sites or jewellery might make headlines, but for scientists, this kind of discovery is only meaningful if we can tell how old the artefacts are. So when chemist Willard Libby developed radiocarbon dating in , it was a breakthrough for archaeology and he was awarded a Nobel prize for his achievement. Nowadays people take radiocarbon technology for granted and many people think you can use radiocarbon on any human remains. But my team may have found the key: DNA dating. To understand why we need DNA dating, you need to know what radiocarbon dating is. It allows us to date organic material that is younger than 50, years based on the chemical reactions that the body exchanges with the environment after death.

I n a interview with the Albright Institute, Prof. Israel Finkelstein extolled the merits of radiocarbon dating in archaeology. According to this theory, the monumental Iron iia structures traditionally dated to the reigns of David and Solomon in the early 10th century b. Finkelstein has long claimed his low-chronology position can be proved by carbon dating.

How Accurate is Carbon Dating?

How reliable is radiocarbon dating? Updated 7 August c Radiocarbon dating, which is also known as carbon dating, is one widely used radiometric dating scheme to determine dates of ancient artifacts. In discussions of the age of the Earth and the antiquity of the human race, creationists often assail perceived weaknesses in radiocarbon dating. Henry M.
