But it is already clear that the carbon method of dating will have to be recalibrated and corrected in some cases.Scientists at the Lamont-Doherty Geological Laboratory of Columbia University at Palisades, N.Since its conception by Willard Libby in 1949, it has been invaluable to the discipline.In fact, many important archaeological artifacts have been dated using this method including some of the Dead Sea Scrolls and the Shroud of Turin.Carbon-14 is produced in the atmosphere when neutrons from cosmic radiation react with nitrogen atoms: C ratio of 0.795 times that found in plants living today. Solution The half-life of carbon-14 is known to be 5720 years.​ Radioactive decay is a first order rate process, which means the reaction proceeds according to the following equation: is the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay.

This assumption is backed by numerous scientific studies and is relatively sound.

New research shows, however, that some estimates based on carbon may have erred by thousands of years.

It is too soon to know whether the discovery will seriously upset the estimated dates of events like the arrival of human beings in the Western Hemisphere, scientists said.

Y., reported today in the British journal Nature that some estimates of age based on carbon analyses were wrong by as much as 3,500 years.

They arrived at this conclusion by comparing age estimates obtained using two different methods - analysis of radioactive carbon in a sample and determination of the ratio of uranium to thorium in the sample.
