The results of calibration are often given as an age range.In this case, we might say that we could be 95% sure that the sample comes from between 1375 cal BC and 1129 cal BC.See also ORAU's Explanation of Radiocarbon Results.Radiocarbon dates should always be reported either as `percent modern' or years `before present' (BP).There are two main methods used for calculating age ranges from the calibration curve: The first method to be employed was called the `intercept method' because it can be done by drawing intercepts on a graph.This method will tell you the years in which the radiocarbon concentration of tree rings is within two standard deviations of your measurement (e.g.For older periods we are able to use other records of with idependent age control to tell us about how radiocarbon changed in the past.

The second is directly derived from this on the assumption that the half-life of radiocarbon is 5568 years and the amount of radiocarbon in the atmosphere has been constant.These are the basis for the calibrations performed by the programs like CALIB and Ox Cal. Calibration of radiocarbon determinations is in principle very simple.
