Carbon 14 is continually being created in the Earth's atmosphere by the interaction of nitrogen and gamma rays from outer space.The different isotopes of carbon do not differ appreciably in their chemical properties.This resemblance is used in chemical and biological research, in a technique called carbon labeling: carbon-14 atoms can be used to replace nonradioactive carbon, in order to trace chemical and biochemical reactions involving carbon atoms from any given organic compound. Jericho is just one example of the discrepancy between historical and C14 dates for the second millennium B. C14 dates are consistently 100–150 years earlier than historical dates. is based on pottery, which, in turn, is based on Egyptian chronology.Follow the links below to learn more about radiocarbon dating.
