In , Willard Libby proposed an innovative method for dating organic materials by measuring their content of carbon, a newly discovered radioactive isotope of carbon. Known as radiocarbon dating, this method provides objective age estimates for carbon-based objects that originated from living organisms. Willard Libby — , a professor of chemistry at the University of Chicago, began the research that led him to radiocarbon dating in
This document discusses carbon dating and its uses in determining the age of once-living materials. Carbon dating works by measuring the amount of carbon remaining in organic material. It has a half-life of about 5, years and can date materials up to 60, years old. Examples given where carbon dating has been applied include dating the Dead Sea Scrolls to BC, determining the Shroud of Turin originated in the 13th century, and estimating meteorite exposure times on Earth. Archaeology also relies heavily on radiocarbon dating. Read less. AI-enhanced description.
Radiocarbon dating is an analysis method based on the measurement of the radioactive C isotope of carbon that accumulates in organisms during their life and decays after their death. Radiocarbon dating is used to estimate the age of biological samples and materials of organic origin, such as fossils and historical objects, along with some inorganic samples that contain carbon. In archaeology and fossil research, radiocarbon dating is used to study the past conditions and environments on Earth.
