1946 In 1946, Willard Libby proposed an innovative method for dating organic materials by measuring their content of carbon-14, a newly discovered radioactive isotope of carbon. Known as radiocarbon dating, this method provides objective age estimates for carbon-based objects that originated from living organisms.
Which material requires the smallest amount for radiocarbon dating?
Any organic material that is available in sufficient quantity can be prepared for radiocarbon dating. Modern AMS (accelerator mass spectroscopy) methods require tiny amounts, about 50 mg. AMS technology has allowed us to date very small
