As he explained to Sciences et Avenir, it is "a piece of the shroud sample, which his Tucson laboratory received on 14 April 1988” - which he had cut, set aside and assumed something of a caretaker role for.

For the first 1988 analyses, the Vatican had permitted only a few milligrams of the shroud to be taken for analysis by three laboratories, in Tucson (USA), Zurich (Switzerland) and Oxford (England).

The measurements were carried out independently in three accelerator mass spectrometry (AMS) laboratories located at the University of Arizona, Tucson, Arizona, USA, Oxford University, Oxford, England, and ETH-Hönggerberg, Zürich, Switzerland with assistance for certification and data analysis provided by the British Museum.

What Rogers discovered was that the crazy idea seemed to be right. 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. After the results had been leaked, twenty-one scientists from the University of Oxford, the University of Arizona, the Institut für Mittelenergiephysik in Zurich, Columbia University, and the British Museum wrote in a peer-reviewed paper published in Nature in 1989: The results of radiocarbon measurements at Arizona, Oxford and Zurich yield a calibrated calendar age range with at least 95% confidence for the linen of the Shroud of Turin of AD 1260 - 1390 (rounded down/up to nearest 10 yr).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.
