No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.

Suess explained the phenomenon by the fact that the increased industrial use of fossil carbon in coal and in oil changed the ratio between the dead carbon C12 and the C14 (radiocarbon) in the atmosphere and therefore also in the biosphere.He is credited to be the first scientist to suggest that the unstable carbon isotope called radiocarbon or carbon 14 might exist in living matter. Libby and his team of scientists were able to publish a paper summarizing the first detection of radiocarbon in an organic sample. Libby who first measured radiocarbon’s rate of decay and established 5568 years ± 30 years as the half-life. Libby was awarded the Nobel Prize in Chemistry in recognition of his efforts to develop radiocarbon dating.Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.Presenti tra gli altri all'operazione, oltre ai due scienziati summenzionati, c'erano il cardinale Ballestrero con quattro sacerdoti, Luigi Gonella, il rappresentante dell'Accademia Pontificia delle Scienze, i fotografi e il cineoperatore.
