根据铀系不平衡和铀的线性积累模型，对具有重要人类学意义的海德堡和陶塔维尔骨骼进行了电子自旋共振(ESR)测年。给出了由ESR测年结果得到的天然辐射总剂量(Td)计算年龄的理论公式和图解。由于考虑了铀在开放系统化石骨骼中的堆积，该模型将ESR年龄显著偏移到老一侧。
Electron spin resonance (ESR) dating of anthropologically important Heidelberg and Tautavel bones has been made based on a model of uranium-series disequilibrium and a linear accumulation of uranium. Theoretical equation and graphic solution are presented to obtain the age from the total dose of natural radiation (TD) derived from the result of ESR dating. The model shifts the ESR ages considerably to the old side as the accumulation of uranium into an open-system fossil bone was taken into account.
