在大多数已建立的发光测年方法中，使用90Sr/90Y放射性核素的比值为样品提供参考实验室剂量。最近推出了一种小型x射线辐照器（瓦里安VF-50J），作为传统放射源的替代方案。给出了在测年技术中是否可能使用小型x射线辐照器的测试结果。评估x射线辐照器的方面包括考虑测量的光激发发光信号和x射线管电流与剂量率之间的关系，以及不同剂量率下等效剂量的依赖关系。测试性能与加热石英的使用有关。
In most established method for luminescence dating, the ratio of 90Sr/90Y radionuclides has been employed to provide reference laboratory doses to sample. Recently a small X-ray irradiator (Varian VF-50J) was introduced as an alternative to the traditionally used radioactive sources. Test results are presented whether the use of the small X-ray irradiator is possible in the dating technique. Aspects of the assessment of the X-ray irradiator include consideration of the measured optically stimulated luminescence signal and the relationship between X-ray tube currents and dose rates, as well as the dependence of equivalent dose for various dose rates. The test performances are assessed in relation to use with heated quartz.
