“…When water that contains radon is used in the home for showering, washing dishes, and cooking, radon gas escapes from the water and goes into the air [3]. The radon from water contributes to the total inhalation risk associated with radon in indoor air [4,5].…”

Radon is the most harmful natural contaminant in the indoor atmosphere of the buildings. The noble gas, after cigarette smoke, is the biggest cause of lung cancer, and today the study of its diffusion, distribution, and concentration around the world has attracted many researchers in the field of radiation protection and environmental health. Typically, output data obtained from traditional methods of measuring radon concentration in indoor buildings is limited to information on the average radon concentration. Although these data are highly valuable in identifying buildings with a high risk of radon, it can be misleading to identify the real danger for residents of these buildings. This study aims to investigate the effects of water temperature and water flow rate on radon concentration and distribution inside the showers. Numerical simulations were conducted using CFD. Also, radon concentration in water was determined by the radon detector AlphaGUARD and is used as input in CFD simulation. The results showed that variations in the water flow rate have more influence on radon distribution than the changes in water temperature. Experiments were performed by measuring radon concentrations at different times in the shower room using monitor Radon Scout Plus. The annual effective dose of radon concentration in the shower room was also investigated.

“…Radon is a radioactive gas that is absorbed in sewage that can penetrate buildings by tap water or showers [1][2][3]. The water is the most significant cause of radon indoors [4][5][6]. However, the calculation of the distribution of radon concentrations arising from water is critical for determining the radiation exposure obtained from radon inhalation and its indoor progeny.…”

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.

“…SSNTDs material is light weight, small volume, electronics free, easy to process and very cheap comparing to any active detectors. These detectors are used to measure the radon concentration in the environmental samples [4][5]. LR-115 type II is a cellulose nitrate (C 6 H 8 O 9 N 2 ) material, which used to detect alpha particles.…”
