Abstract

This article focuses on the study of the Oklo natural nuclear reactors in Gabon and their potential relationship with the emergence of early complex life forms in the same region. Discovered in 1972 through isotopic anomalies in uranium ore, the Oklo site contains evidence of sustained natural fission reactions that occurred around 2 billion years ago, with reactor conditions similar to modern pressurized water reactors. Advanced nuclear physics software has been used to model isotopic concentrations, neutron spectra, and energy deposition over time, providing insights into both the biological effects of natural radiation on early life and the long-term behavior of nuclear waste storage. The article also discusses related subcritical uranium-rich environments, such as uranium mines and lagoons, and emphasizes the interdisciplinary collaboration needed between geologists and radiobiologists to understand the influence of natural radioactivity on life evolution and radioactive waste management.
