本文概括地叙述了铀系方法,简要地报道了我们用铀系法鉴定三个碳酸盐国际标准样的结果,以及所应用的化学流程、电沉积制备α薄源技术条件、铀和钍同位素α谱和数据处理的步骤;对比和讨论了各国实验室的数据,结果表明,我们测得的数据与国际主要实验室的数据是一致的。
This article provides an overview of uranium-based methods and briefly reports on the results of our identification of three carbonate international standards using the uranium system, as well as the applied chemical processes, the technical conditions for the preparation of a-thin source by electrodeposition, uranium and thorium isotopes α spectra and data processing steps were compared and discussed. The data of the laboratories in different countries were compared and discussed. The results show that the data we measured are consistent with the data of major international laboratories.
