The isotopes produced during the natural nuclear reactor 2 billion years ago were produced in certain ratios because of the relative sizes of their nuclear cross sections, which depend on the fine structure constant.
The isotopes used in radio dating are produced by spontaneous transmutation over time, which is governed by entirely different processes.
