Abstract
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.
