| Abstract: | The concentration levels and distributions of indoor ^222Rn/^220Rn were the key parameters in the subjects refered to the accessment and protection of Health hazards of indoor ^222Rn/^220Rn. At first the real physical model was established based on the factors that influenced indoor ^222Rn/^220Rn values. Then CFD technology was used to study the volume-averaged values and the three-dimensional distributions of indoor ^222 Rn/^220Rn by the different ventilation strategies with the fixed outdoor concentra tions and the exhalation rate of the walls. |
