Radiocarbon dating the earth
In the traditional model of science, radiocarbon has little to do with the age of the Earth, since its lifespan is so short.
However, RATE is attempting to fit all radiometric dating into a young earth model.
Carbon isotopes are generally measured through the use of a machine called the accelerated mass spectrometer.
A small portion of the sample is put into the machine which then vaporizes it.
Taking advantage of the distinct mass of individual isotopes, the machine distinguishes the C from all of the other atoms and molecules present and is able to count the individual atoms.
Charcoal, cloth, bone, or any other material that contains organic carbon can be dated using an accelerated mass spectrometer.
The RATE research in the area of radiocarbon has focused on the "blank" sample date.Theoretically, radiocarbon techniques have the ability to date samples to around 75,000 years, but the working threshold of reliable dating is around 50,000 years.Samples significantly older than this have very little or even no measurable C left.It can combine with other atoms and molecules such as oxygen to create carbon dioxide, or CO2.Through the process of photosynthesis, plants absorb carbon dioxide which contains C left in a sample to accurately measure without contamination.
