C arbon-14 dating involves the decay of radioactive C-14, which has a half flippancy of 5770 years. This makes this method useful for dating of recent fossils, with good accuracy, up to 50,000 years back. After 5770 years, half of the carbon-14 in a fossil decays to nitrogen-14. Since the ratio of carbon-12 to carbon-14 in a living organism clay the same as i...If you want to get a estimable essay, order it on our website:
