"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].

The archaeologist Colin Renfrew (1973) called it the development of this dating method 'the radiocarbon revolution' in describing its great impact upon the human sciences.

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

The Half Life is independent of the physical state (solid, liquid, gas) temperature, pressure, the chemical compound in which the nucleus finds itself, and essentially any other outside influence.

It is independent of the chemistry of the atomic surface, and independent of the ordinary physical factors of the outside world.

Animals eat plants, and some eat other animals in the food chain.

Carbon follows this pathway through the food chain on Earth so that all living things are using carbon, building their bodies until they die.

Depending on the isotope, its Half Life may range from a few fractions of a second to several billion years. The Half Life of Uranium-238 is 4,500,000,000 years.

There is even a radioactive isotope of carbon, carbon-14. C-14 has two extra neutrons and a half-life of 5730 years.

Willard Libby, the principal scientist, had worked in the team making the nuclear bomb during World War 2, so he was an expert in nuclear and atomic chemistry.
