Study on Air Radon Concentration and Radiation Dose in a Uranium Mining Area in South China
Measure and evaluate the air radon concentration and radiation dose of residents in a uranium mining area in southern China,measure indoor and outdoor radon concentrations in 9 major villages,calculate annual effective doses,study residents'health risks,and propose corresponding protective suggestions.The results showed that the indoor radon concentration in the study area ranged from 113.1～189.8 Bq/m3,with an average of 151.5 Bq/m3,significantly higher than the average levels in China and globally;The annual effective dose range caused by indoor radon concentration is 5.66～9.50 mSv/a,with an average of 7.58 mSv/a;The outdoor dose is 0.97～1.27 mSv/a,with an average of 1.12 mSv/a.The average annual effective dose is 8.70 mSv/a,which is 3.14 times the global average.Research has shown that the lungs and respiratory tract receive the highest radiation dose outside the chest,with an average of 20.87 mSv/a and 25.04 mSv/a.It is recommended to reduce indoor radon concentration and minimize potential harm to residents'health by increasing ventilation,using environmentally friendly materials,and regularly monitoring radon concentration.
