How Far Back Is Carbon Dating Accurate

(ICR) have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon (C-14) 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-14 dating, using the question-answer format that has proved so useful to lecturers and debaters. Question: How does carbon-14 dating work? Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon). Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes. When the organisms die, they stop incorporating new C-14, and the old C-14 starts to decay back into N-14 by emitting beta particles. The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate. So, if we me

using the properties of radiocarbon (14C), a radioactive isotope of carbon. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists. Libby received the Nobel Prize carbon dating is only accurate to for his work in 1960. The radiocarbon dating method is based on the fact carbon dating error margin that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting radiocarbon

How Does Carbon Dating Work

combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire 14C by eating the plants. When the animal or plant dies, it stops exchanging carbon with https://ncse.com/cej/3/2/answers-to-creationist-attacks-carbon-14-dating its environment, and from that point onwards the amount of 14C it contains begins to decrease as the 14C undergoes radioactive decay. Measuring the amount of 14C in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died. The older a sample is, the less 14C there is https://en.wikipedia.org/wiki/Radiocarbon_dating to be detected, and because the half-life of 14C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by radiocarbon dating are around 50,000 years ago, although special preparation methods occasionally permit dating of older samples. The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained. Research has been ongoing since the 1960s to determine what the proportion of 14C in the atmosphere has been over the past fifty thousand years. The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age. Other corrections must be made to account for the proportion of 14C in different types of organisms (fractionation), and the varying levels of 14C throughout the biosphere (reservoir effects). Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s. Because the time it takes to convert biological materials to fossil fuels is substantially longer than the time i

Climate records from a Japanese lake are set to improve the accuracy of the dating technique, carbon dating which could help to shed light on archaeological mysteries such as why Neanderthals became extinct. Carbon dating is used to work out the age of organic material — in effect, any living thing. The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate. Organisms capture a how far back certain amount of carbon-14 from the atmosphere when they are alive. By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question. But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock. The clock was initially calibrated by dating objects of known age such as Egyptian mummies and bread from Pompeii; work that won Willard Libby the 1960 Nobel Prize in Chemistry. But even he “realized that there probably would be variation”, says Christopher Bronk Ramsey, a geochronologist at the University of Oxford, UK, who led the latest work, published today in Science. Various geologic, atmospheric and solar processes can influence atmospheric carbon-14 levels. Since the 1960s, scientists have started accounting for the variations by calibrating the clock against the known ages of tree rings. As a rule, carbon dates are younger than calendar dates: a bone carbon-dated to 10,000 years is around 11,000 years old, and 20,000 carbon years roug

do not realize is that carbon dating is not used to date dinosaurs. The reason? Carbon dating is only accurate back a few thousand years. So if scientists believe that a creature lived millions of years ago, then they would need to date it another way. But there is the problem. They assume dinosaurs lived millions of years ago (instead of thousands of years ago like the bible says). They ignore evidence that does not fit their preconceived notion. What would happen if a dinosaur bone were carbon dated? - At Oak Ridge National Laboratory, Scientists dated dinosaur bones using the Carbon dating method. The age they came back with was only a few thousand years old. This date did not fit the preconceived notion that dinosaurs lived millions of years ago. So what did they do? They threw the results out. And kept their theory that dinosaurs lived "millions of years ago" instead. This is common practice. They then use potassium argon, or other methods, and date the fossils again. They do this many times, using a different dating method each time. The results can be as much as 150 million years different from each other! - how’s that for an "exact" science? They then pick the date they like best, based upon their preconceived notion of how old their theory says the fossil should be (based upon the Geologic column). So they start with the assumption that dinosaurs lived millions of years ago, then manipulate the results until they agree with their conclusion. Their assumptions dictate their conclusions. So why is it that if the date doesn't fit the theory, they change the facts? Unbiased science changes the theory to support the facts. They should not change the facts to fit the theory. A Dinosaur carbon dated at 9,890 and 16,000 years old NOT millions of years old like evolutionists claim I have documentation of an Allosaurus bone that was sent to The University of Arizona to be carbon dated. The results were 9,890 +/- 60 years and 16,120 +/- 220 years. "We didn't tell them that the bones they were dating were dinosaur bones. The result was sample B at 16,120 years. The Allosaurus dinosaur was supposed to be around 140,000,000 years. The samples of bone were blind samples." This test was done on August 10, 1990 Comment from a reader: "O
