Abstract

In order to study the distribution characteristics and potential health risks of typical radionuclides in water around the uranium mining area, the activity concentration of radionuclides in shallow groundwater and river water around the area was analyzed and measured. The improved Nemero comprehensive pollution index method was used to evaluate radioactive pollution level, the cancer risks for people of different ages were assessed by the health risk assessment model. The results showed that activity concentrations of²³⁸U, ²²⁶Ra and ²³²Th in groundwater (0.012~0.102, 0.013~0.036, 0.002~0.033Bq/L)and river water (0.001~0.066, 0.013~0.034, 0.001~0.013Bq/L) did not exceed the standards stipulated by the WHO for drinking-water quality, but far higher than the average values in Jiangxi Province. The nuclides' activity concentration in the river water continuously decreased as water flowed, while no obvious trend was observed for spatial distribution of nuclides. The comprehensive pollution index in river water was higher than that in groundwater:The peak value for river water was 9.21 which was heavy pollution, while the peak value for groundwater was 6.83 which is medium pollution. Results of health risk assessment indicated that the cancer risk for infants and children was higher than that for adults. The lifetime cancer risk for infants exceeded the maximum value of 5.0×10^-5 regulated by ICRP, and meantime the risk values for children and adults were respectively 33.3% and 16.7% higher than standards. Even if the other water samples did not exceed the standard, they were higher than the negligible risk level of 10^-6 recommended by USEPA, and therefore indicating potential cancer risk. The carcinogenic risk level of nuclides decreased in the order of ²²⁶Ra > ²³²Th > ²³⁸U. Therefore, more attention should be focused on the study of ²²⁶Ra and ²³²Th in drinking water around uranium mining area.
