The environmental radioactivity levels of two typical uranium mines in the south of China were investigated and analysed. According to the characteristics of uranium mines, the relevant parameters, including the surface gamma ray dose rate, concentration of radon in the air and concentration of radionuclides in the soil and surface water, of two uranium mines were evaluated and analysed. The results show that residents in the mining area were exposed to average maximum annual effective doses of 1.69 and 1.58 mSv due to the inhalation of radon and its daughters, while the employees received 2.59 and 1.87 mSv, respectively. Residents in the mining area were exposed to average maximum annual effective doses of 0.77 and 0.69 mSv due to gamma ray, while the employees received 1.64 and 1.33 mSv, respectively.
