Abstract: Tritium (3H) in excess of the atmospheric values was found at volcanic Lakes Pavin (France), Laacher (Germany) and Nemrut (Turkey), as well as Kilauea Volcano at Hawaii (USA) and other volcanoes. Because 3H has a short half-life of 12.3 years, this tritium and the resulting 3He must have formed recently in the Earth. This result suggests that nuclear reactions may generate a significant amount of tritium in the interior of the Earth, although we have not yet learned what the reaction mechanism may be responsible. The nuclear reaction that can be responsible for tritium production in the Earth is probably a new research field in physics science. Nuclear reactions that generate tritium might be a source of “missing” energy (heat) in the interior of the Earth. Finding in-situ 3H in the mantle may exhibit an alternative explanation of 3He origin in the deep Earth.

Key words: Tritium, 3He/4He ratio, anomalous nuclear reaction, Earth’s interior
