Shroud turin dating radiocarbon
The shroud allegedly was in a fire during the early part of the 16th century and, according to believers in the shroud's authenticity, that is what accounts for the carbon dating of the shroud as being no more than 650 years old.
Actually, it has two images, one frontal and one rear, with the heads meeting in the middle.These initial tests show no significant reaction - even though the sensitivity of the measurements is sufficient to detect contamination that would offset the age by less than a single year.This is to be expected and essentially confirms why this sort of contamination has not been considered a serious issue before.However there are also a number of reasons to think that carbon monoxide contamination is not likely to have had a significant effect: The only way to see if this sort of contamination is possible is to do experimental work on modern linen.
The key question is whether carbon monoxide reacts to any significant extent with linen.
It has been noted that if the shroud were really wrapped over a body there should be a space where the two heads meet.
