Large amount of radon is emitted to the atmosphere in uranium mining, which have a certain degree of radioactive pollution to the environment. Through the establishment of the radon diffusion model,the article carried out reasonable theoretical estimates for cal-culating the degree and range of radon pollution caused by uranium mining,and discussed how to select the appropriate height of the exhaust vents and the key protection area within the corresponding neighborhood under different natural conditions. The results show that the radon pollution level is not high around the exhaust vents when...
