From this, scientists concluded that the flax plants from which the linen in the Shroud of Turin was made were grown in medieval times, long after the death of Jesus.

In the next stage, the graphite derived from the shroud sample, consisting of a mixture of stable carbon isotopes with radioactive carbon 14, was bombarded by heavy cesium atoms.

This process knocked carbon atoms loose from the graphite, endowed some of them with electric charges and sent them toward the accelerator.

Instruments working at lower energies cannot make such sharp distinctions. Donahue said that in dealing with a postage stamp-size sample from the shroud, the linen was first ''carefully cleaned, using both chemical and mechanical methods.'' Next, the sample was burned in oxygen, thereby converting the carbon in its molecules into carbon dioxide gas.

The gas was then reduced to pure carbon in the form of graphite by heating the gas in the presence of iron powder.

Pieces the Size of Postage Stamp Instead, the Vatican opted for a more advanced method that is more precise and requires the destruction of a much smaller sample of material, roughly the size of a postage stamp.
