Abstract
This article presents the results of evaluating the feasibility of methods for analyzing the radionuclide and chemical composition of natural waters. There are numerous chemical, physical, physico-chemical, and core-physical methods for analyzing the radionuclide and chemical composition of natural waters. In natural waters, in most cases it is determined - solids, pH values, anions - Cl-, NO2-, NO3-, СО32-, HCO3-, SO42-, and their sum, cations - Ca+, Mg+, Na++K+, Fe3+, NH4 and their sum and concentration of metals Mn, Pb, Cu, Zn, Co, Cr, Ni.

In plain English
Water was sampled at six points: the Zarafshan in Navoi city, the Amu Darya at Sarimoy settlement, at Cholish bridge and at Jumurtau, the Damkhoja irrigation network and the Amu–Bukhara canal at Gijduvan bridge; all six are rivers, canals or irrigation channels. Anions and cations were measured by photocolorimetry, manganese, lead, copper, zinc, cobalt, chromium and nickel by atomic absorption, and the gross alpha and beta activity of the dry residue with a UMF-2000 radiometer. Uranium-238, radium-226, thorium-232 and polonium-210 are also given.
Mineralisation is 1.2 g/L in the Zarafshan at Navoi; 1.6, 1.8 and 2.1 g/L in the Amu Darya at Sarimoy, Cholish bridge and Jumurtau; 0.85 g/L in the Damkhoja network; and 1.12 g/L in the Amu–Bukhara canal, against a norm of 1 g/L for drinking water. Lead is 0.10–0.17 mg/dm³ in all six samples, at or above the 0.10 mg/dm³ permitted for household water, and manganese is highest at Navoi, 4.98 mg/dm³.
Uranium-238 is 0.53–0.81 Bq/L, radium-226 0.014–0.032 Bq/L, thorium-232 0.16–0.37 Bq/L and polonium-210 0.008–0.052 Bq/L. Gross alpha activity is 0.17–0.20 Bq/L and gross beta 0.22–0.60 Bq/L, not above the norms of 0.2 and 2.0 Bq/L for drinking water. The authors conclude that these methods are suitable for assessing the radionuclide and chemical composition of natural waters.
