| Summary: | Заглавие с экрана Thorium-uranium typification has been proposed for the first time for 22 deposits and occurrences of radon-rich waters in the southern part of West Siberia. The studied waters are extremely diverse in gas and chemical composition, TDS, and geochemical parameters of the medium. The concentrations of natural radionuclides are (mg/dm3 ): 238U (3.68•10-7-1.40), 232Th (4.04•10-7-2.16•10-3). The activity of dissolved radon (222Rn) varies from 4 to 2257 Bq/dm3 . The 232Th/238U ratio varies from 2.63•10-5 to 26, and its maximal values were detected in ultrafresh, thermal, alkaline waters with the reductive geochemical medium in which thorium possesses increased migration capacity. Quite the contrary, uranium migrates in the oxidative geochemical setting. |
