Abstract
Marked warming of a climate has one of the results the degradation of a permafrost. Estimation of this degradation rates are necessary for considering at studying resources and qualities of underground waters, construction of long-term constructions, a burial place of radioactive waste, reconstruction of paleoclimate, etc. In this article it is considered theoretical bases and an opportunity of use developed by the author’s technique, which is based on isotope systematics δ2Н, δ18О, 234U/238U and U/He, 3Н/3Не dating of groundwater, and also correlations between them for reconstruction of rates of the permafrost degradation.
