Time-dependent changes in dose rates generally need to be considered in luminescence dating due to the dynamic character of the geosphere. Nevertheless, this aspect is rather marginally treated in the literature. The present paper describes the methodology of including temporal variations of overburden, moisture content and radionuclide activity into the calculation of dating results. Consideration of possible occurrences of variable dose rates has consequences for fieldwork procedures as well as for the choice of appropriate methods of radionuclide determination. A program code for age calculation by luminescence methods called ADELE v2017 is presented which implements several examples of temporal dose rate variations and layered structures with inhomogeneous distribution of dose rate relevant elements. The impact of variable dose rates on age data is illustrated by applying ADELE v2017 to several case studies.

变化是发光测年中唯一恒定的时间依赖性剂量率

由于地球圈的动态特性,在发光测年中通常需要考虑剂量率随时间的变化。然而,这方面在文献中很少被提及。本文介绍了将覆盖层,水分含量和放射性核素活度的时间变化纳入测年结果计算的方法。考虑可能出现的剂量率变化对现场工作程序以及放射性核素确定的适当方法的选择都有影响。提出了一种用于通过发光方法计算年龄的程序代码,称为ADELE v2017,该程序代码实现了时间剂量率变化和剂量率相关元素不均匀分布的分层结构的几个示例。
