Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Most carbon on Earth exists as the very stable isotope carbon, with a very small amount as carbon The barbarians of the north were capable of designing complex structures similar to those in the classical world. Soon after the publication of Libby's paper in Scienceuniversities around the world began establishing radiocarbon-dating laboratories, and by the end of the s there were more than 20 active 14 C research laboratories.

Since the surface ocean is depleted in 14 C because of the marine effect, 14 C is removed from the southern atmosphere more quickly than in the north.
