In the paper the issues of using of natural zeolites from Eastern Transbaikal for solving geoecological problems are considered. Chemical and mineral composition of natural zeolites from Eastern Transbaikal is presented. Main directions of the application of zeolite containing rocks at mining industry and for environmental protection at atomic power provision mining enterprises are outlined. Experimental investigations for decontaminating of waste water of industrial enterprises from radionuclide and other contaminants. Characteristics of sorption with natural zeolites 137Cs from solution 0.1 and 1.0 mol/l sodium nitrate are represented. Sorption dependences 137Cs from concentration of sodium ions in solution and from size of sorbent granules are established. Results of investigation of sorption with natural zeolite of radionuclide 90Sr and ions Са2+.
