... effective dose of the lung inside the model house when the windowswere closed, was 111± 10.20mSv y 1 ( Table 2). When the windows opened in the wind direction or opposite the wind direction, the radon annual -1 effective dose of the lung decreased to 2.46 ± 0.86 and 4.16 ± 0.81mSvy , respectively and also, when crossed windows opened but in silent condition (no wind), theradon annual effective dose of the lung was reduced to -1 5.43 ± 0.86 mSvy (Figure 1).The reason for these value reductions is due to differential pressure between indoor and outdoor air which results to reduce the values at the time of measurement. So when there is a relation between indoor and outdoor air, it can be assumed as the presence of fresher outdoor air inside of dwellings and can be so effective and useful tool to dilute the indoor radon levels and its benefits will be the reduction of indoor radon hazards especially for the radon related critical organ of the lung. For B samples (severely hot soil samples), the mean (±SD) radon annual effective dose of the lung -1 when the windows were closed, was 10.44 ± 1.26mSvy (Table 2). When the windows were openin the wind direction andopposite of the wind direction, the radon annual effective dose of the lung decreased to 1.92±0.66 -1 and 3.39 ±0.90mSv y respectively, and also when crossed windows were opened, but in silent condition(no -1 wind), the radon annual effective dose of the lung was reduced to 2.75 ±0.91mSvy (Figure 2). Moving to C samples, the mean (±SD) radon annual effective dose of lung when the crossed windows -1 were closed, was 3.27 ± 0.60 mSv y (Table 2), When cross-windows were opened in the wind direction or opposite the wind direction, the radon annual effective dose of the lung was decreased to 1.74 ±0.48 and ...
