After the war he became very interested in peaceful applications of atomic science.He and two students first measured the "half-life" of radiocarbon.The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.Libby of the University of Chicago after the end of World War 2.The half-life refers to the amount of time it takes for half the radiocarbon in a sample of bone or shell or any carbon sample to disappear.Libby found that it took 5568 years for half the radiocarbon to decay.Welcome to the K12 section of the Radiocarbon WEBinfo site.
