The results, depending on the calibration, can be quite different. Naturally, different statistical models for interpretation of the same data will produce different results. After processing the data with all these scientific tools, most archaeologists “improve” the given dates in accordance with broader archaeological and historical considerations.For all these reasons, contrasting dates have been reached in the ongoing chronological debate concerning the Iron Age.The question I would like to raise is whether radiocarbon dating is really more precise, objective and reliable than the traditional way of dating when applied to the problem of the date of the transition from Iron I to Iron IIa.This question is sharpened in light of the fact that the uncertainty in the usual radiocarbon readings (plus or minus 25 years or so) may be as large as the difference in dates in the debate. Measuring the remaining carbon-14 content in “long-term” organic samples, such as wood, will provide the date of growth of the tree, rather than the date of the archaeological stratum in which the sample was found.

Therefore a complex procedure known as calibration has been developed, which converts radiocarbon test results to calendar years by relating these results to dendrochronologically dated tree-ring samples.The calibration curve is revised periodically as more data are continuously accumulated.But the absolute date after calibration depends on which calibration formula is used. This uncertainty ranges from 20 years (for high-precision dating) through intermediate values of 50–100 years, and in some cases up to 100–150 years. For interpreting the results, different statistical models are used by different researchers.The differences in the various dates for the transition from Iron I to Iron IIa are too small to be helped much by radiocarbon dating.Hopefully, as radiocarbon dating continues to develop, it will eventually be more useful in solving the problems of Iron Age chronology.
