Radio carbon dating carried out in 1988 was performed on an area of the relic that was repaired in the 16th century, according to Ray Rogers, who helped lead the Shroud of Turin Research Project (STRP).
He came to his conclusion after re-examining a theory from two amateur scientists that he had earlier dismissed as being from "the lunatic fringe".
The results provide conclusive evidence that the linen of the Shroud of Turin is mediaeval.
The Shroud of Turin , which many people believe was used to wrap Christ's body, bears detailed front and back images of a man who appears to have suffered whipping and crucifixion.
He said: "The cotton fibres were fairly heavily coated with dye, suggesting they were changed to match the linen during a repair.
"I concluded that area of the shroud was manipulated by someone with great skill. The worst possible sample for carbon dating was taken.

However, in a 1990 paper Gove conceded that the "arguments often raised, …The Shroud of Turin (Turin Shroud), 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. Shredding the samples would not solve the problem, while making it much more difficult and wasteful to clean the samples properly.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 around 30 AD. 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".But Cesare Nosiglia, the Archbishop of Turin and "pontifical custodian of the shroud," said the special display on Holy Saturday "means that it represents a very important testimony to the Passion and the resurrection of the Lord," The Telegraph reported.The burial shroud purports to show the imprint of the face and body of a bearded man.
