Radiocarbon dating measures radioactive isotopes in once-living organic material instead of rock, using the decay of carbon-14 to nitrogen-14. Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old.May 20, 2011
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
