National Historic Chemical Landmarks: Honoring the Discovery of Radiocarbon Dating
On Oct. 10, the American Chemical Society will dedicate a National Historic Chemical Landmark at the University of Chicago in Chicago, Illinois, in honor of Willard Libby’s discovery of radiocarbon dating. Libby’s method for dating organic materials by measuring their content of carbon-14 provides objective age estimates for carbon-based objects that originated from living organisms. Libby’s discovery greatly benefitted the fields of archaeology and geology by allowing practitioners to develop more precise historical chronologies across geography and cultures.
Libby was inspired Serge Korff’s 1939 discovery that the bombardment of the atmosphere by cosmic rays produced neutrinos. Korff predicted that the reaction between these neutrons and nitrogen-14, which predominates in the atmosphere, would produce carbon-14, also called radiocarbon.
