Libby and others (University of Chicago) devised a method of estimating the age of organic material based on the decay rate of carbon-14.Carbon-14 is produced in the atmosphere when neutrons from cosmic radiation react with nitrogen atoms: C ratio of 0.795 times that found in plants living today. Solution The half-life of carbon-14 is known to be 5720 years. Radioactive decay is a first order rate process, which means the reaction proceeds according to the following equation: is the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay.The Muslims count the Prophet’s departure from Mecca, or the Hegira, as their beginning at AD 662.The Mayan calendar used 3114 BC as their reference.
