Beyond that timespan, the amount of the original C formed by irradiation of nitrogen by neutrons from the spontaneous fission of uranium, present in trace quantities almost everywhere.For these samples, other dating methods must be used.These factors affect all trees in an area, so examining tree-ring sequences from old wood allows the identification of overlapping sequences.In this way, an uninterrupted sequence of tree rings can be extended far into the past.ICR creationists claim that this discredits C-14 dating. Answer: It does discredit the C-14 dating of freshwater mussels, but that's about all.

The study of tree rings led to the first such sequence: tree rings from individual pieces of wood show characteristic sequences of rings that vary in thickness because of environmental factors such as the amount of rainfall in a given year.Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow.Therefore it should come as no surprise that creationists at the Institute for Creation Research (ICR) have been trying desperately to discredit this method for years.These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.Furthermore, if a sample has been contaminated, scientists will know about it.
