How Does Carbon Dating Work

Liquid scintillation counting is another radiocarbon dating technique that was popular in the s. Known as radiocarbon dating, this method provides objective age estimates for carbon-based objects that originated from living organisms. We would, obviously, have to assume that the candle has always burned at the same rate, and assume an initial height of the candle. If a date obtained by radiometric dating does not match the assumed age from the geologic column, the radiometric date will be rejected. Radiocarbon dating has also been used to date the extinction of the woolly mammoth and contributed to the debate over whether modern humans and Neanderthals met.
