Carbon dating fake

SAN FRANCISCO, March 21, 2010 — Two decades of atomic bomb testing in the atmosphere are yielding an unexpected bonus for consumers, scientists reported here today at the 239th National Meeting of the American Chemical Society (ACS).

It’s a new test to determine whether that Bordeaux or burgundy is from a fine vintage year and commands premium price or actually is a counterfeit vin ordinaire or cheap plonk worth much less. D., who headed the research, said that misrepresenting the vintage — the year the wine was made — is an ongoing problem. Some years bring perfect growing conditions for vineyards in a country or region of a country and the grapes produce exceptional wines that command premium prices.

By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.

But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.

Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes.
