In Table 2, the letters indicate the Tukey significant difference among the average concentrations of ²³²Th, ²³⁸U, and ⁴⁰K across the column. The Tukey’s multiple pairwise honestly significant (THSD) statistical test, the column with different letter(s) are significantly different at p ≤ 0.0 5 confidence level. Meaning of the letters: “a” is very highly significant; “b” is very significant; “c” is significant; “d” is non-significant
