Abstract
Origin of 3He in the Earth is a mystery. Lacking a production mechanism, scientists assume 3He was trapped in the Earth, when the Earth was formed. In contrast to this assumption, we have found 3He and 3H concentrations in excess of the atmospheric values in the deep waters of the volcanic Lakes Pavin (France), Laacher (Germany) and Nemrut (Turkey). This paper reports the result of finding 3H in these three volcanic lakes that appear to originate from the mantle. Because 3H has a half-life of 12.3 years, this 3H and the resulting 3He must have formed recently in the mantle and not be part of a primordial reservoir. The nuclear reactions that generate tritium might be a source of “missing” energy in the interior of the Earth.
