In the late 1940s, an American physical chemist named Willard Libby first developed a method to measure radioactivity of carbon-14, a radioactive isotope.The idea of scientifically dating the shroud had first been proposed in the 1960s, but permission had been refused because the procedure at the time would have required the destruction of too much fabric (almost 0.05 sq m ≅ 0.538 sq ft). P.), which involved about 30 scientists of various religious faiths, including non-Christians. Testore performed the weighting operations while Riggi made the actual cut.
