Natural radionuclides and toxic elements in the border areas of rivers flowing into Kazakhstan from Kyrgyzstan

The paper reports on the study of the radiation situation and the degree of contamination with natural radionuclides and toxic elements of 11 transboundary rivers and the Big Chu Channel at the points of their inflow into Kazakhstan from Kyrgyzstan. The methods of radiometry, IGS, XRF, MS-ICP, OES-I...

Description
Summary:The paper reports on the study of the radiation situation and the degree of contamination with natural radionuclides and toxic elements of 11 transboundary rivers and the Big Chu Channel at the points of their inflow into Kazakhstan from Kyrgyzstan. The methods of radiometry, IGS, XRF, MS-ICP, OES-ICP, RChA were used. It was established that the radiation background in the examined areas is high, but does not pose a risk to human health. In the majority of the transboundary watercourses, the chemical toxicity of waters exceeds for 2–12 times the regulatory value set in the Republic of Kazakhstan for drinking water. Uranium contributes 37% to this indicator.
