The technique arises from radiocarbon being continually produced in the upper atmosphere by cosmic rays while it is continually decaying, so the atmospheric concentration has reached a fairly steady equilibrium.
More processing tends to introduce more contamination.Contamination and instrument background are sometimes collectively referred to as “total background.” Taylor and Southon have characterized six general types of total background, each of which has multiple specific sources .For our purposes, we will group these contributions into three general classes of contamination and background: The first contribution often results in sample-position-dependent variations in radiocarbon content, thus is often detectable by measuring multiple pieces of the same sample.Muller suggested that particle accelerators be used to separate the atoms, allowing the radiocarbon atoms to be counted directly instead of waiting for them to decay.It was hoped that this would enable dating of much smaller and perhaps much older samples.This equilibrium continues through plants to herbivores and through them to carnivores.
Once an organism dies, its carbon ceases exchanging with atmospheric carbon but continues decaying with a half-life of about 5730 years.The ICR (Institute for Creation Research) recently spent eight years on a project known as RATE (Radioisotopes and the Age of The Earth).The RATE team claims the results have yielded convincing and irrefutable scientific evidence of a young earth.John Baumgardner, a geophysicist with expertise in tectonic modeling, presents experimental data claiming to show that all biological material contains intrinsic radiocarbon, no matter how old that material may be thought to be [1, 2].He makes additional claims that even non-biological carbonaceous material contains intrinsic radiocarbon.But the amount of contamination is generally impossible to quantify.
