Comparisons of statistical analysis results between five methods using gamma spectrometry and a control group for measuring the radioactivity of uranium were performed to suggest the optimal method. In the statistical tests including linear regression, and Pearson’s correlation all gamma spectrometry methods correlated with the control group method though they had each disadvantage. The Student’s t-test results for a novel method 5 including a ²³⁰Th contribution, were 0.986 (²³⁵U) and 1.821 (²³⁸U), respectively. It had the advantage of being more accurate when evaluating the activity of ²³⁵U and ²³⁸U simultaneously. The novel method 5 can thus be recommended over others.

比较了使用伽马光谱法的五种方法与测量铀放射性的对照组之间的统计分析结果，以提出最佳方法。在包括线性回归和皮尔逊相关性在内的统计检验中，所有伽马能谱方法都与对照组方法相关，尽管它们各有缺点。^包括230 Th 贡献的新方法 5的学生t检验结果分别为 0.986 ( ²³⁵ U) 和 1.821 ( ²³⁸ U)。它的优点是同时评估²³⁵ U 和²³⁸ U 的活性时更准确。因此可以推荐新方法5而不是其他方法。
