From that point forward, the amount of Carbon in materials left over from the plant or animal will decrease over time, while the amount of Carbon will remain unchanged. There are three different naturally occurring varieties isotopes of carbon: Their recent analysis of sediment from the largest freshwater lake in northeast China showed that its carbon clock stopped ticking as early as 30, years ago, or nearly half as long as was hitherto thought. Scientists can use this ratio to help determine the starting amount of 14C. Since the s, scientists have started accounting for the variations by calibrating the clock against the known ages of tree rings. Researchers could then disregard the date and try other methods of dating the object. The illustration below shows the three isotopes of carbon. The interpretation of past events is in question. Another possible avenue is C13, which has a small but non-zero neutron absorption cross section.
