Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon-14 there is left in an object a man called willard f libby pioneered it at the university of. Radiocarbon dating of organic material is based on the concentrations of radioactive carbon-14 in a sample remaining after the organisms’ death over the past two decades, the method has been refined greatly by combining it with dendrochronology, the study of the environmental effects on the width of tree rings through time. For example, radiocarbon dating, which measures the ratios of carbon-14 to carbon-12 to estimate an age, cannot be used on the pottery found at the ruins of different cities an unearthed building in jerusalem has been dated to the time of david based on the pottery fragments found at its level.
