Carbon 14 or radiocarbon dating


Carbon-14 dating does not produce ages in the millions of years, as do some other types of radioisotope dating.C dating consists of measuring the amounts of carbon-14 and carbon-12, and sometimes C-13, in a sample.Carbon-14 dating cannot be applied to materials that have no C dates are less than that figure.It is sometimes thought possible to extend the dating range a few half-lives, so one occasionally sees dates as old as 70,000 years or more.



In recent years, forensic scientists have started to apply carbon-14 dating to cases in which law enforcement agencies hope to find out the age of a skeleton or other unidentified human remains.However, the researchers suggested that soft tissue radiocarbon content would be transferred to, and preserved in, the pupal cases of insects whose larvae feed on these tissues.Such insects are simply another link in the food chain.To determine year of birth, the researchers focused on tooth enamel.

Adult teeth are formed at known intervals during childhood.

Barring any future nuclear detonations, this method should continue to be useful for year-of-birth determinations for people born during the next 10 or 20 years.
