The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.

14C also enters the Earth's oceans in an atmospheric exchange and as dissolved carbonate (the entire 14C inventory is termed the carbon exchange reservoir (Aitken, 1990)).

Plants and animals which utilise carbon in biological foodchains take up 14C during their lifetimes.

Renfrew (1973) called it 'the radiocarbon revolution' in describing its impact upon the human sciences.

Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.

Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones.
