新风换气对室内氡浓度的影响
Effect of Fresh Air Ventilation on Indoor Radon Concentration
摘要
Abstract
The radon concentration of laboratory for radon simulation (LRS) was measured by the RAD7 radon monitor, and the effect of the different fresh air ventilations on indoor radon concentration was studied and analyzed. The indoor radon concentration of LRS can be accumulated up to 2 000 Bq/m3 and the average radon exhalation rate of the LRS is 14. 5 Bq · m~2 · h-1. Furthermore, when the fresh air enters into the LRS continuously, the indoor radon concentration decreases exponentially with the increase of time. The equilibrium radon concentration and equilibrium time of LRS decrease exponentially with the increase of the rate of fresh air ventilation. In addition, the indoor radon concentration increases by accumulation with the decrease of the rate of fresh air ventilation.关键词
