Abstract	The average level of indoor radon concentration for the residence in the uranium ore district is 282Bq/m3 and the maximum value can up to 570 Bq/m3 which exceed the national top limited value (200Bq/m3). 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 waste rock yards to indoor radon concentration is only 38.08Bq/m3, accounting for 16.3% of the total indoor radon concentration. But the average value of indoor radon exhalation rate from the ground surface is 0.06 Bq/m2•s. By calculating, radon concentration caused by it is 154Bq/m3, whose contribution to indoor radon concentration is 65.8%. It can be seen that indoor radon of the residence mainly comes from radon precipitation of the soil, followed by the radon in the atmospheric environment. The study can provide a reference to reducing radon pollution of the housing and radiation protection of the residents.
