Abstract
Results of the studies into the features of the geochemistry of radon waters from the Zaeltovsky-Mochishche zone of Novosibirsk city are reported. Radon waters are fracture, cold with the temperature of 6-10 оC, they occur at a depth of 50-200 m. In the hydrogeological section, neutral and weakly alkaline waters are developed, with рН from 6,9 to 7,8, mainly with the calcium hydrocarbonate and calcium-sodium hydrocarbonate composition, with total mineralization from 322 to 895 mg/dm3. The concentrations of 222Rn in water-saturated zones of granites vary from 308 to 1521 Bq/dm3, while in the wells drilled into hornstones radon content varies within the range 37-241 Bq/dm3. The concentrations of 238U and 226Ra do not exceed 0.098 mg/dm3 and 3.5∙10-7 mg/dm3, respectively.
