Shroud of turin carbon dating problems “the radiocarbon sample has completely different chemical properties than the main part of the shroud relic,” rogers told bbc news (“turin” 2005). thanks to the gi bill, rogers was able to complete his education at the university of arizona, majoring in chemistry. evidence of medieval fakery includes the shroud’s lack of historical record prior to the mid-fourteenth century—when a bishop reported the artist’s confession—as well as serious anatomical problems, the lack of wraparound distortions, the resemblance of the figure to medieval depictions of jesus, and suspiciously bright red and picturelike “blood” stains which failed a battery of sophisticated tests by forensic serologists, among many other indicators. a relevant list of rogers' scientific publications can be found on the web (explosives science). fact, the radiocarbon sample (a small piece cut from the “main body of the shroud” [damon 1988, 612]) was destroyed by the testing. both were specifically reported by famed microanalyst walter mccrone (1996, 85) who was commissioned to examine samples taken by the shroud of turin research project (sturp).
