A comparative study on indoor radon concentrations affected by ventilation rates

Worldwide, indoor radon exposure is considered to be the second leading cause of lung cancer, after smoking. Ventilation is believed to be one of the effective methods to mitigate radon concentration. This comparative study is designed to demonstrate how exactly ventilation rate affects the indoor radon concentration aiming to encourage people to mitigate the indoor radon concentration by using matched ventilation mode. From the collected data, we can find out that at any level of ventilation rates there is always a good reduction effect on radon concentration. Nevertheless, the lower rates of ventilation could not reduce the radon concentration below the action level, which may lead to potential health issues. Thus, it is quite important and necessary for us to understand that not only ventilation but also ventilation rates matter a lot if we want to reduce the radon concentration to a relatively safe level.
