Abstract

Three methods of calculation in Chemical Physics are used to study how the isotopic exchange could affect the radiocarbon age of the Shroud of Turin. The basic hypothesis is that a fire in the year 1532 caused an isotopic exchange reaction between the air and the fabric of linen. According to this model, molecules of carbon dioxide from the air exchanged isotopes  by isotopes  with the monomers of cellulose of linen. This would be the reason why the dating laboratories have measured a radiocarbon age of 600 years instead of 2000 years.

Key words: Shroud of Turin, physics, radiocarbon, hypothesis.
