Abstract

Excess of uranium-234 in natural water (ratio 234U/234U 1 in comparison to the equilibrium value as 1 by activity) correlates with global climate variations, increasing during warm and decreasing during cold periods. The hurricane disequilibrium of 234U/234U 10 are found in groundwater. Based on mathematical models, it is shown that such anomalies are the result of a geologically long stay of aquifers in a frozen state in the past and the subsequent melting of ground ice with the formation of “revived” water. Non-freezing film moisture present in permafrost rocks make a decisive contribution to the formation of hurricane 234U excess.
