How accurate is carbon 14 dating
Because of this relatively short half-life, radiocarbon is useful for dating items of a relatively recent vintage, as far back as roughly 50,000 years before the present epoch.
But, as is clear even from the very brief discussion in the previous paragraph, radiocarbon dating can say nothing one way or the other about whether the earth is many millions of years old, since such dates are far beyond this method's range of resolution.But no one actually knows the starting point conditions when things began to form to figure out its age. Stipp, “Excess Radiogenic Argon in Young Subaerial Basalts From Auckland Volcanic Field, New Zealand,” 33 (1969): 1485-1520).Scientific literature shows that the zero starting point assumption is not always valid. 2- The assumption that the rate of decay has remained constant over time.The half-life of C, it can only give dates in the thousands-of-year range and not millions.Radiocarbon doesn’t work well on objects much older than twenty thousand years for such objects have small amounts of C-14 left in them.
