This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature. C is by far the most common isotope, while only about one in a trillion carbon atoms is C C is produced in the upper atmosphere when nitrogen N is altered through the effects of cosmic radiation bombardment a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope. The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous. It is naturally unstable and so it will spontaneously decay back into N after a period of time. It takes about 5, years for half of a sample of radiocarbon to decay back into nitrogen.

Radiocarbon dating has transformed our understanding of the past 50, years. Professor Willard Libby produced the first radiocarbon dates in and was later awarded the Nobel Prize for his efforts. Radiocarbon dating works by comparing the three different isotopes of carbon. Isotopes of a particular element have the same number of protons in their nucleus, but different numbers of neutrons. This means that although they are very similar chemically, they have different masses. The total mass of the isotope is indicated by the numerical superscript.

Carbon Dating

The Shroud of Turin , a linen cloth that tradition associates with the crucifixion and burial of Jesus , has undergone numerous scientific tests, the most notable of which is radiocarbon dating , in an attempt to determine the relic 's authenticity. In , scientists at three separate laboratories dated samples from the Shroud to a range of — AD, which coincides with the first certain appearance of the shroud in the s and is much later than the burial of Jesus in 30 or 33 AD. The idea of scientifically dating the shroud had first been proposed in the s, but permission had been refused because the procedure at the time would have required the destruction of too much fabric almost 0. The development in the s of new techniques for radio-carbon dating, which required much lower quantities of source material, [8] prompted the Catholic Church to found the Shroud of Turin Research Project S.

New scientific tests on the Shroud of Turin, which went on display Saturday in a special TV appearance introduced by the Pope, dates the cloth to ancient times, challenging earlier experiments dating it only to the Middle Ages. Pope Francis sent a special video message to the televised event in the Cathedral of Saint John the Baptist in Turin, Italy, which coincided with Holy Saturday, when Catholics mark the period between Christ's crucifixion on Good Friday and his resurrection on Easter Sunday. The Vatican, tiptoeing carefully, has never claimed that the foot linen cloth was, as some believers claim, used to cover Christ after he was taken from the cross 2, years ago. Francis, reflecting that careful Vatican policy, on Saturday called the cloth, which is kept in a climate-controlled case , an "icon" -- not a relic.
