Enea, the National Agency for New Technologies, Energy and Sustainable Economic Development, has published a report on five years of experiments conducted in the ENEA center of Frascati on the “shroud-like coloring of linen fabrics by far ultraviolet radiation”. “Simply put: we tried to understand how the Shroud of Turin was imprinted by an image so special that it constitutes its charm, and poses a great and very radical challenge, “to identify the physical and chemical processes capable of generating a color similar to that of the image on the Shroud.”

“However, Enea scientists warn, “it should be noted that the total power of VUV radiations required to instantly color the surface of linen that corresponds to a human of average height = 34 thousand billion watts makes it impractical today to reproduce the entire Shroud image using a single laser excimer, since this power cannot be produced by any VUV light source built to date (the most powerful available on the market come to several billion watts )”.
