Radionuclides in Soils, Waters, and Surface Air in Certain Mountainous Areas of Uzbekistan

The results of γ-spectroscopic research of the concentrations and vertical distributions of natural 226 Ra, 232 Th, 40 K, technogenic 137 Cs, and cosmogenic 7 Be radionuclides in soils, the radon flux density in the surface air, and the radon concentration in waters in some regions of the Nurata, Karatepa, Chakilkalyan, and Gissar mountains of Uzbekistan are presented. The dependence of these values on the physiographic characteristics of areas, the intensity of natural and anthropogenic processes occurring on them, weather, and other factors was revealed.
