Abstract

Abstract The main physical and chemical characteristics of soils, including their particle-size and mineralogical compositions, were determined as a result of comprehensive radioecological studies on two test plots in the northeast of Stavropol krai within the Chograi-Caspian semi-desert landscape and the Chograi-Ragulinskii landscape of grass steppes. Background concentrations of natural radionuclides (NRs) 40K, Th, and U, of technogenic radionuclides 90Sr and 137Cs, and of their isotopic (Sr, Cs) and non-isotopic (Ca, K) carriers were estimated in the upper (0–20 cm) soil layer. Geo-accumulation indices (Igeo) calculated for heavy metals Cs, Sr, Th, and U, were
