"studies on the radiocarbon sample from the shroud of turin". the actual provenance of these threads is uncertain, as gonella was not authorized to take or retain genuine shroud material, but gonella told rogers that he excised the threads from the center of the radiocarbon sample. however, in a 1990 paper gove conceded that the "arguments often raised, … that radiocarbon measurements on the shroud should be performed blind seem to the author to be lacking in merit … lack of blindness in the measurements is a rather insubstantial reason for disbelieving the result. evidence for the skewing of the c-14 dating of the shroud of turin due to repairs.^ turin shroud 'could be genuine as carbon-dating was flawed stephen adams in the daily telegraph 10 apr 2009.
