Discrepancies in the radiocarbon dating area of the turin shroud
that discarding the blind-test method would expose the results – whatever they may be – to suspicion of unreliability.
On 12 December 2003, Rogers received samples of both warp and weft threads that Luigi Gonella claimed to have taken from the radiocarbon sample before it was distributed for dating.The Shroud of Turin, a linen cloth that tradition associates with the crucifixion and burial of Jesus, has undergone numerous scientific tests, the most notable of which is radiocarbon dating, in an attempt to determine the relic's authenticity. group initially planned to conduct a range of different studies on the cloth, including radio-carbon dating. The six labs that showed interest in performing the procedure fell into two categories, according to the method they utilised: In 1982, the S. Samples were taken on April 21, 1988, in the Cathedral by Franco Testore, an expert on weaves and fabrics, and by Giovanni Riggi, a representative of the maker of bio-equipment "Numana".In 1988, scientists at three separate laboratories dated samples from the Shroud to a range of 1260–1390 AD, which coincides with the first certain appearance of the shroud in the 1350s and is much later than the burial of Jesus in 30 or 33 AD. Testore performed the weighting operations while Riggi made the actual cut.The lab representatives were not present at this packaging process, in accordance with the protocol.The labs were also each given three control samples (one more than originally intended), that were: and communicated their results to the British Museum.
