**Abstract:** We find that the experimental data of the α-decay half-lives for 627 nuclei are in good agreement
with Benford’s law, which states that the frequency of the appearance of each figure, 1–9, as the first
significant digit, follows a logarithmic distribution favoring the smallest value. In order to generalize the
applicability of Benford’s law, we systematically investigate the data of the total half-lives for 3177 nuclides
in their ground and isomeric states, where the half-lives of many nuclei are determined by β-decay and
spontaneous fission.We find that they are also in excellent agreement with Benford’s law, although they are
determined by different interactions such as strong, weak and electromagnetic interactions. The possible
physics behind them is discussed. Moreover, Benford’s law can be used to test theoretical models or
methods
