Radiocarbon dating of organic materials


Scientists can measure the amount of carbon in a piece of old wood for instance, and say that because there is only a certain amount left, the tree died years ago. Most carbon consists of the isotopes carbon 12 and carbon 13, which are very stable. How does radiocarbon dating work? But measuring how much carbon is in a formerly living thing compared to carbon and doing some math with what is called a half-life you can date things to within a certain range. Archaeologists also take steps when selecting and recovering samples to minimise this potential problem. In order to conduct dating on an artifact you need a sample of it. AliasAlice 12, Contributions Why can radiocarbon dating not be used on some artifacts? The most common isotope is carbon or 12 C , which according the article makes up The half-life is about years. And since scientists know exactly how long an amount of 14 C takes to decay, they can compare the amount of 14 C in a specimen to the amount of 14 C a modern piece of organic matter and calculate the age of the specimen. The different elements of the carbon exchange reservoir vary in how much carbon they store, and in how long it takes for the 14 C generated by cosmic rays to fully mix with them. Radiocarbon Dating All organic matter contains carbon, which is an element.
