Return to List of Skeptical Questions
The honest skeptical inquirer ponders . . .
Could radiation have caused the images on the Shroud of Turin?
Probably not! Radiation (electromagnetic radiation; ionizing particles such as protons, electrons, and alpha particles; and non-ionizing particles such as neutrons) almost certainly could not have formed the caramel-like substance that makes up the images. Enough energy to induce a chemical change in the super-thin carbohydrate film that holds the image would have visibly altered the characteristic molecular arrangement, the fibrillar structure of the flax fibers. That did not happen.
The image bearing layer can be removed with adhesive and with reducing agents such as diimide leaving clear, unablated fibers.

Shroud of Turin and the Skeptical Inquirer
Fact:
The 1988 carbon 14 dating used invalid samples snipped from a
discrete medieval repair. Furthermore, kinetics constants for the
loss of vanillin from lignin indicates that the cloth is at least
twice as old as the dates determined by the carbon 14 dating with
the faulty samples.
By some estimates, from
examination of documenting photographs, there is sufficient new
thread (about 60%) to allow adjusting the cloth's date to
approximately the first century.
Fact :
The images are formed by a brownish, complex conjugated carbon
substance within a carbohydrate layer of starch fractions no thicker
than 1/100 the diameter of a human hair.
The images are probably the
product of an amino/carbonyl reaction.
Fact :
The bloodstains are real blood. The blood is unusually red for
old blood.
The blood probably stayed red and
did not turn black as blood normally does because trace chemicals
found in the starch fractions are hemolytic. Also, the blood is rich
in bilirubin, a bile pigment produced when a human body is under
severe traumatic stress. Bilirubin is bright red and stays red.
Fact :
There is a faint, superficial face image on the back of the cloth.
This supports the hypothesis of an
amino/carbonyl reaction.
Fact :
There are sufficient descriptive historical records to suggest that
the Shroud of Turin is the Edessa cloth (ca. before 544 to 944 CE)
and the Bucoleon Palace grave cloth of Constantinople (ca. 944 -
1204).
Fragmentary evidence suggests that
the Edessa Cloth originated in Jerusalem in the 1st century and that
it is the burial cloth of Jesus of Nazareth.
