Carbon dating experts from universities in oxford, zurich and arizona proved that the shroud originated in the 14th century and thus could not be an imprint of jesus and yet many now argue that process was flawed ian wilson, a historian who has written a number of books on the subject, believes the shroud could indeed be genuine.

Carbon-14 dating is something that you hear about in the news all the time find out how carbon-14 dating works and why carbon-14 dating is so accurate.
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon (14 c), a radioactive isotope of carbon the method was developed by willard libby in the late 1940s and soon became a standard tool for archaeologists.
