| Abstract: |
| To assess characteristics of radionuclides pollution and its influence in uranium mine and its surrounding areas, 20 groundwater samples were collected in wet, normal, and dry season, respectively, to measure concentrations of 238U, 230Th, 226Ra, 210Pb, and 210Po. Internal exposure dose caused by drinking water around uranium mine was evaluated by national standard. The results show that no 230Th is checked out in groundwater of studied area. Average concentration of 238U, 226Ra, 210Pb, and 210Po is 1.31 μg/L, 28.09 mBq/L, 13.98 mBq/L, and 12.68 mBq/L, respectively . Total internal exposure dose caused by radioactive nuclides is 2.44×10-5 Sv, lower than the reference level from WHO, with no significant hazards to people. |
