牛津放射性碳加速器单元（ORAU）最近的研究表明，考古骨头中的明胶超滤在许多情况下可以去除低分子量污染物。这些元素有时可能具有不同的放射性碳年龄，除非移除，否则可能严重影响结果，特别是在对超过两到三个14C半衰期的骨头进行定年时。在这项研究中，这种方法被应用于来自不列颠群岛的旧石器时代晚期和早期晚期的样本。在许多情况下，修订的结果引起对这些时期的年表进行认真的重新考虑。版权所有©2006约翰威利父子有限公司
Recent research at the Oxford Radiocarbon Accelerator Unit (ORAU) has shown that ultrafiltration of gelatin from archaeological bone can, in many instances, remove low molecular weight contaminants. These can sometimes be of a different radiocarbon age and, unless removed, may severely influence results, particularly when dating bones greater than two to three half‐lives of 14C. In this study this methodology is applied to samples of Late Middle and Early Upper Palaeolithic age from the British Isles. In many instances the results of redating invite serious reconsideration of the chronology for these periods. Copyright © 2006 John Wiley & Sons, Ltd.
