Answer Give two Advantages of Nuclear Power. Name one Thing which can not be Dated using Carbon Dating. Before the advent of radiocarbon dating, the fossilized trees had been dated by correlating sequences of annually deposited layers of sediment at Two Creeks with sequences in Scandinavia.

Korff predicted that the reaction between these neutrons and nitrogen, which predominates in the atmosphere, would produce carbon, also called radiocarbon. This was demonstrated in by an experiment run by the British Museum radiocarbon laboratory, in which weekly measurements were taken on the same sample for six months. Similarly, groundwater can contain carbon derived from the rocks through which it has passed. Prior to carbon dating methods, the age of sediments deposited by the last ice age was surmised to be about years. This article will explain how radiocarbon dating method?
