Consider just a few sources:
In 1978 one hundred and twenty hours of scientific studies of the Shroud were conducted. Activities included visible, ultraviolet and infrared spectroscopy light, ultraviolet and phase microscopy, infrared thermography, x-radiographic imaging, electron microscopy, computer analysis, photographic imaging with special films, microchemical analysis, etc. -- Frederick T. Zugibe, M.D., "The Cross and the Shroud", (New York: Paragon House) (Revised ed., 1988), 119 - 122.
Radiocarbon Dating of the Shroud of Turin 1988
Very small samples from the Shroud of Turin have been dated by accelerator mass spectrometry in laboratories at Arizona, Oxford and Zurich. As Controls, three samples whose ages had been determined independently were also dated. The results provide conclusive evidence that the linen of the Shroud of Turin is mediaeval.
... Scientific and popular publications have presented diverse arguments for both authenticity and possible methods of forgery. A variety of scientific theories regarding the shroud have since been proposed, based on disciplines ranging from chemistry to biology and medical forensics to optical image analysis. According to former Nature editor Philip Ball, "it's fair to say that, despite the seemingly definitive tests in 1988, the status of the Shroud of Turin is murkier than ever. Not least, the nature of the image and how it was fixed on the cloth remain deeply puzzling". The shroud is one of the most studied artifacts in human history, and one of the most controversial.
