放射性碳测年法对考古研究至关重要，在许多遗址中，骨头是唯一可以测定年代的样本。为了确定年代而破坏骨头所造成的损失并不重要，而破坏与所研究的文明有关的衣服或木制物品则令人遗憾。用骨头来确定一个考古水平的年代也比用木头或手工艺品更合乎逻辑，因为这些东西不一定与当时的遗址同时代。然而，在14c骨测量中经常出现严重的错误，这主要是因为在化学处理过程中难以完全消除大量的污染物。
DATING by the radiocarbon method is of primary importance for archaeological studies and on many sites bones are the only samples which can be dated1. The losses arising from the destruction of bones for dating purposes is not very important, whereas it is a pity to destroy clothes or wooden items associated with the civilization being studied. It is also more logical to use bones for dating an archaeological level than to use wood or artefacts, for example, which are not necessarily contemporary with the site occupation2. There are, however, frequent and often important errors in14C bone measurements which arise chiefly because of the difficulty of eliminating completely the numerous pollutants during chemical treatment.
