During the period of a plant's life, the plant is taking in carbon dioxide through photosynthesis, which is how the plant makes energy and grows.
Animals eat plants, and some eat other animals in the food chain.
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.
The job of a radiocarbon laboratory is to measure the remaining amounts of radiocarbon in a carbon sample.
This is very difficult and requires a lot of careful work to produce reliable dates.
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.
After the war he became very interested in peaceful applications of atomic science.
He and two students first measured the "half-life" of radiocarbon.
