Carbon 14 dating flawed
For the last 21 years most have considered it to be a medieval fake, after the 1988 tests dated it as being made between 12.
The result overturned 10 years of hope among Christians that it was real, after the first scientific tests found evidence of blood and serum stains.
The net effect of this is that all living organisms have the same radiocarbon to stable carbon ratio as the atmosphere.
Once an organism dies the carbon is no longer replaced.
It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50,000 years ago - about when modern humans were first entering Europe.
For radiocarbon dating to be possible, the material must once have been part of a living organism.
It seemed likely they were the remains of the Scandinavian Vikings of the Great Heathen Army who wintered in Repton over a millennium ago during 873–874.
Eyewitness accounts indisputably reported the army’s historical presence during the latter 800s, so many modern historians concluded that these mass-grave skeletons were those very Vikings.
Common materials for radiocarbon dating are: The radiocarbon formed in the upper atmosphere is mostly in the form of carbon dioxide. Because the carbon present in a plant comes from the atmosphere in this way, the radio of radiocarbon to stable carbon in the plant is virtually the same as that in the atmosphere.
By consuming plant-eating animals (cattle, sheep, goats, swine, etc.), humans ingest carbon-14 indirectly.
A major assumption affecting the mathematics of radiocarbon dating is that human skeletons contain residual carbon-14 acquired predominantly from terrestrial (i.e., land-food-based) diets.
"I concluded that area of the shroud was manipulated by someone with great skill. The worst possible sample for carbon dating was taken.
"It consisted of different materials than were used in the shroud itself, so the age we produced was inaccurate." In the video, made shortly before he died of cancer in March 2005, he said: "I came very close to proving the shroud was used to bury the historic Jesus."This latest evidence, to be broadcast in The Turin Shroud: New Evidence at 8pm on Sunday on the Discovery Channel, is the latest chapter in the shroud's history.
This fact should always be remembered when using radiocarbon dates.
