Numerical and Experimental Investigation of Radon Dispersion in Typical Ventilation Schemes of Bathroom

Human exposure to radon indoor air has become a great concern. Using the Computational Fluid Dynamics (CFD) technique, we investigated the efficiency of ventilation systems for indoor radon reduction. In order to optimize ventilation for the bathroom, we applied the impact of ventilation on radon distribution in the bathroom, in which we characterized airflow and radon level regulation in the ventilated space. Radon Scout Plus is used to measure radon amounts in the bathroom as part of the validation process. The simulation results are consistent with the experimental outcomes. In addition, the annual effective dosage of Radon in the bathroom has been calculated.
