Surface water chemistry and content of radionuclides 238U, 226Ra, and 222Rn were studied in both natural and technogenic landscapes of Southern Yakutia. The technogenically disturbed landscapes of the El’konskii Uranium Ore Region showed intense migration of these radionuclides in water from dumps of radioactive rocks that had formed during large-scale exploration works for radioactive ore in the...
The article presents the results obtained in studying variations of the concentrations of ion composition, and nutrients in the surface waters of Southern Yakutia in the construction zone of the Amur–Yakutsk Railway Main Line, as well as in streams in the territory of the Neryungri Coal and Aldan Gold-Mining regions. In 2007–2012, the concentrations of major ions in the 15 examined watercourses varied...
