A carbon dating

After about 10 half-lives, the amount of radiocarbon left becomes too miniscule to measure and so this technique isn't useful for dating specimens which died more than 60,000 years ago.

Another limitation is that this technique can only be applied to organic material such as bone, flesh, or wood. Carbon Dating - The Premise Carbon dating is a dating technique predicated upon three things: Carbon Dating - The Controversy Carbon dating is controversial for a couple of reasons.

First of all, it's predicated upon a set of questionable assumptions.

It is naturally unstable and so it will spontaneously decay back into N-14 after a period of time.

It takes about 5,730 years for half of a sample of radiocarbon to decay back into nitrogen.

Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.

Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7).
