摘要：
The average level of indoor radon concentration for the residence in the uranium ore district is 282Bq/m(3) and the maximum value can up to 570 Bq/m(3) which exceed the national top limited value (200Bq/m(3)). Indoor radon pollution of the residence is very serious. In order to find out the reason of radon pollution, the main environmental factors are investigated. Through the calculations of Gaussian atmospheric diffusion model and simulation verificationthe it is found that the contribution of airborne pollution source terms including uranium mine ventilation shaft, heap leaching field and w...
