关于牙釉ESR测年计算方法的讨论

A discussion on calculation method of tooth enamel ESR dating

一种新的针对薄层的牙釉样品的电子自旋共振测年方法———ROSYESR测年程序是采用one -group传递理论计算牙釉中的 β剂量率 ,其结果比原有的DATA程序计算出的 β剂量率小 ,但与统计学中的蒙特卡罗理论计算结果更为接近。本文还采用ROSY和DATA两种方法计算了湖北郧县遗址的 6个牙釉样品的年龄 ,并进行了比较。

A new ESR dating method--ROSY ESR dating program is introduced. It enabled us to calculate the beta attenuation in thin layers of tooth enamel based on 'One Group' theory. This approach leads to average beta doses which are significantly lower than those from Grün's DATA software, but more close to the results from calculation based on Monte Carlo data. The ages of six tooth enamel samples from Yunxian site, Hubei, were determined and compared with each other by using ROSY and DATA programs.
