This paper presents a fast and reproducible method for determination of uranium content in ammonium uranyl carbonate (AUC) and U3O8 obtained from it. The effects of high activity and specific chemical composition of the samples were minimized by adapting the radiochemical procedures for analysis of a small amount of samples. Measurements were made by alpha-spectrometry and ICP-MS. The results show that the applied procedures are stable with significant yield and can be successfully used for analysis of AUC and U3O8. Comparison of the data obtained by alpha-spectrometry and by ICP-MS shows that the measured values are in good coincidence.

测定碳酸铀酰铵 (AUC) 和八氧化三铀 (U3O8) 中的铀含量

本文提出了一种快速且可重现的方法，用于测定碳酸铀酰铵 (AUC) 中的铀含量，以及由此获得的 U3O8。通过调整用于分析少量样品的放射化学程序，将样品的高活性和特定化学成分的影响降至最低。通过α光谱法和ICP-MS进行测量。结果表明，应用程序稳定，产率显着，可成功用于 AUC 和 U3O8 的分析。α 光谱法和 ICP-MS 获得的数据的比较表明，测量值符合良好。
