Radio carbon dating information
It is called 'radio'-carbon, because it is 'radioactive'.This means that its atomic structure is not stable and there is an uneasy relationship between the particles in the nucleus of the atom itself.Welcome to the K12 section of the Radiocarbon WEBinfo site.The aim here is to provide clear, understandable information relating to radiocarbon dating for the benefit of K12 students, as well as lay people who are not requiring detailed information about the method of radiocarbon dating itself.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.Libby found that it took 5568 years for half the radiocarbon to decay.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.
Animals eat plants, and some eat other animals in the food chain.
Eventually, a particle is emitted from the carbon 14 atom, and carbon 14 disappears.
Most of the carbon on Earth exists in a slightly different atomic form, although it is chemically speaking, identical to all carbon.
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.
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)].
