Equation proof carbon 14 dating 50000
Thus by comparing the relative quantity of carbon -12 and carbon -14 in an organic matter excavated scientists can predict the age of the object (R. Where N is the current amount, N_o is the original amount, lambda is the proportionality constant for the growth rate (which is negative for decay), and t is the amount of time that has passed. Source: (Brain, 2014) The half-life of carbon-14 is 5730 years.
It is produced currently at a fairly constant rate in the upper atmosphere through the action of cosmic radiation on Nitrogen-14.The science of archaeology has undeniably enriched mankind’s history and has helped to quench the quest to understand our past cultures in a better way.Understanding the age and period of existence of the excavated fossils and other organic objects will help the archaeologist to unravel human history and evolution in a scrupulous manner (Taylor 24).Then the amount of carbon-12 in the body will not reduce but the amount of carbon-14 undergoes reduction due its radioactivity. Carbon-14 isotope will undergo decay at an exponential rate to form the stable nitrogen-14. The following equation is used to determine the carbon-14 decay.
But studies have showed a slight fluctuation in this ratio over the millennia and hence there is a possibility and consequent discrepancy in calculation too (Currie).
