Radiocarbon dating the Hotwife chat
The lab is based in Miami, Florida, and is the world leader in carbon-14 analyses since 1979.
It has forwarding offices in Australia, Brazil, China, Japan, South Korea, Taiwan, and the UK.
Atmospheric nuclear weapon tests almost doubled the concentration of Radiocarbon dating, also known as the C14 dating method, is a way of telling how old an object is. Plants take up atmospheric carbon dioxide by photosynthesis, and are eaten by animals, so every living thing is constantly exchanging carbon-14 with its environment as long as it lives. In 1958 Hessel de Vries showed that the concentration of carbon-14 in the atmosphere varies with time and locality.
The isotope, Carbon-14, abbreviated as C in a sample.The “radiocarbon revolution” made possible by Libby’s discovery greatly benefitted the fields of archaeology and geology by allowing practitioners to develop more precise historical chronologies across geography and cultures.Willard Libby (1908–1980), a professor of chemistry at the University of Chicago, began the research that led him to radiocarbon dating in 1945.This resource is designed to provide online information concerning the radiocarbon dating method.We hope it will be of occasional use to radiocarbon users and interested students alike.
