Carbon dating of shroud of turin pnty of fish dating
It has been on display only five times in the past century.
When it last was available to the public in 2000, more than 3 million people saw it.
Rowe's new method eliminates the destructive steps of sampling, acid-base washes and burning.
The object is simply placed in a special chamber with a plasma, an electrically charged gas similar to that used in big-screen plasma television displays.
The next viewing will be from April 10 to May 23 in the Turin Cathedral.
Contamination to the shroud could alter the accuracy of the carbon dating.
This bioplastic coating is almost like plaque on teeth, and would have grown especially at the corner of the shroud where it was handled so much.Exposure to years of candle soot in the cathedral and Turin pollution, the drenching with water during the fire, and the accumulation of minuscule fragments of deteriorating ceiling frescos would give the shroud a coating which could in turn skew the carbon-dating results.Moreover, a corner sample which over the years had been handled by many individuals would probably be contaminated.The results match those of conventional carbon dating techniques, they say.They conceded, however, that it would take a significant amount of data to convince museum directors, art conservators and possibly the Vatican that the non-invasive method indeed causes no damage.
