Pushkar'ova R. Exchange of the isotopes of hydrogen in the clay minerals

Research objects: loess-like loam, bentonite, kaolinite. The purpose of research: study of entry of isotopes of hydrogen in structure of clay minerals in normal conditions and under influence of gamma-irradiation; estimation of possibility of using of clay rocks as a geological-geochemical buffer for tritium tritium pollution of environment in places of a dislocation of points of repository of radioactive waste (PRRW). Methods and instrumentation: IR-spectroscopy (UR-10, UR-20), beta-spectroscopy (Quantulus 1220), NGR (ЯГР-4), PMR (РЯ-2301), gamma-irradiation (Со60). Theoretical and practical results, novelty: the exchange of isotopes of hydrogen of an aqueous medium with hydrogen of structural OH-groups of clay minerals in quasinormal conditions for short time is revealed,a number of parameters of an exchange is appreciated, influence of gamma-radiation dose to an exchange of hydrogen isotopes in a system "clay-water" for the first time is learnt, usage of gamma-radiation for acceleration of introduc tion of hydrogen isotopes in structural OH - group is offered; the obtained parameters of hydrogen isotopes exchange allow to evaluate buffer properties of different types of clay minerals for tritium pollution; the path of realization of the obtained results for account of tritium pollution distribution in borders of influence of Kiev PRRW is offered. A degree of introduction: the data about an immobilization of tritium in clay minerals are used at estimation of radioecological influence of tritium in Kharkov PPRW. An orb of usage: repository of radioactive waste (RAW).
