Radiocarbon dating disproved
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.
These results therefore provide conclusive evidence that the linen of the Shroud of Turin is mediaeval. The radiocarbon measurements were done, not at one laboratory, but at three highly regarded institutions. The results provide not just evidence but conclusive evidence. Finally Ray Rogers, who had accepted the carbon dating, decided to disprove a crazy explanation from what he called the lunatic fringe.
Isotopes have the same number of protons but different numbers of neutrons in their nucleus.He was later awarded the Nobel Prize for his efforts.Carbon is a common element found in nearly everything.He concluded that the sample used for carbon dating was not representative of the cloth. Moreover, one of the chemical differences, the amount of vanillin, provided a new clue about the cloth’s age.Samples from the main part of the cloth, unlike the carbon 14 sample area, did not contain any vanillin. After a lengthy peer review process, his findings that the carbon dating was wholly invalid were published in the scientific journal Rogers' published work showing that the carbon dating is invalid has been confirmed by John L Brown, a forensic materials specialist at Georgia Tech in Atlanta, Georgia and by Robert Villarreal and a team of nine scientists at the Los Alamos National Laboratory in New Mexico.
