Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by … Meer weergeven History In 1939, Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had … Meer weergeven The variation in the C/ C ratio in different parts of the carbon exchange reservoir means that a straightforward calculation of the age of a sample based on the amount of C it … Meer weergeven For decades after Libby performed the first radiocarbon dating experiments, the only way to measure the C in a sample was to detect the radioactive decay of individual carbon atoms.
