Abstract

Results of γ-spectroscopic research of concentrations and vertical distributions of natural ²²⁶Ra, ²³²Th, ⁴⁰K, technogenic ¹³⁷Cs and cosmogenic ⁷Be radionuclides in soils, radon flux density in the surface air and radon concentration in waters in some regions of Nurata, Karatepa, Chakilkalyan and Gissar mountains of Uzbekistan are presented in the work. 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.
