The radioactive decay of carbon-14 follows an exponential decay.

Carbon dioxide also permeates the oceans, dissolving in the water.In 1960, he was awarded the Nobel Prize in chemistry for this work.He first demonstrated the accuracy of radiocarbon dating by accurately estimating the age of wood from an ancient Egyptian royal barge for which the age was known from historical documents.Measurements are traditionally made by counting the radioactive decay of individual carbon atoms by gas proportional counting or by liquid scintillation counting.

For samples of sufficient size (several grams of carbon) this method is still widely used in the 2000s.
