Carbon dating range
Thus radiocarbon serves biblical chronology mainly by helping to eliminate large-scale biblical chronology errors arising out of misinterpretation of the biblical text or textual corruption.(For a good example of the role radiocarbon plays in biblical chronology see Is Bryant Wood's chronology of Jericho valid? Once such large-scale errors have been eliminated the precision of biblical chronology rivals that of dendrochronology. Radiocarbon is not generally useful for narrowing the range of such biblical chronology dates further because radiocarbon tends to have poorer precision than biblical chronology.Archeologists use a statistical standard deviation to increase the range of dates for a sample that has been given a C14 date.Radiocarbon dates are usually calculated to one standard deviation.Each of these methods is explained in this section.Radiocarbon dating is a widely applied absolute dating method in archeology.
When the organism dies, the carbon 14 (C14) atoms disintegrate at a known rate, with a half-life of 5,700 years.For example, modern biblical chronology dates Noah's Flood to 3520 /- 21 B. Absolute dating techniques attempt to pinpoint a discrete, known interval in time such as a day, year, century, or millennia.This, in fact, is the most significant factor contributing to loss of precision in radiocarbon dates today.However, this contribution is usually only a few decades.
