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

A tiny part of the carbon on the Earth is called Carbon-14 (C14), or radiocarbon.

Rasmus Nyerup's quote reminds us of the tremendous scientific advances which have taken place in the 20th century.

In Nyerup's time, archaeologists could date the past only by using recorded histories, which in Europe were based mainly on the Egyptian calendar.

After the war he became very interested in peaceful applications of atomic science.

He and two students first measured the "half-life" of radiocarbon.

You can work out that after about 50 000 years of time, all the radiocarbon will have gone.

All plants and animals on Earth are made principally of carbon.Because carbon is very common on Earth, there are alot of different types of material which can be dated by scientists.Below is a list of the different kinds of materials which can be dated: Libby tested the new radiocarbon method on carbon samples from prehistoric Egypt whose age was known.In the 1940s, scientists succeeded in finding out how long it takes for radiocarbon to disappear, or decay, from a sample of carbon from a dead plant or animal.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.

The half-life refers to the amount of time it takes for half the radiocarbon in a sample of bone or shell or any carbon sample to disappear.
