Radiocarbon Dating and Questions. By Kamil Erkan. Libby’s discovery, now known as the carbon (or radiocarbon) technique, was a method that could be used to determine the age of organic remains. The carbon which is formed is radioactive and decays to produce nitrogen again. There is therefore a fixed amount of carbon in the environment which is a balance between the rate at which it is formed in the atmosphere and the rate at which it decays back to nitrogen. How does Carbon Dating work? All living things take in carbon from . Learn about radiation and how it is used as well as the waste and dangers with BBC Bitesize GCSE Physics. Homepage. Radioactive decay is used in carbon dating. Try for your MBA online? Argon - 40 is a stable isotope. The isotope carbon - 14 is created at radioactive dating gcse questions constant rate in the upper atmosphere by cosmic rays acting on nitrogen. Back to Radiation for life index. The amount of carbon in the wood decreases with time as it decays into nitrogen with a half-life of about years. The further back in time that something diedthe less carbon - 14 will be present in it today.
