Does Opening Windows Decrease Radon Levels In Your Home?

Can opening a window effectively reduce radon levels in a building? While opening windows can provide temporary relief by allowing radon to disperse, it’s important to note that this method is only effective in the short term. Once the windows are closed, radon concentrations indoors will swiftly return to their previous levels. The idea of keeping windows open all the time as a long-term solution is impractical due to security concerns and the need to maintain a comfortable indoor climate. Therefore, alternative radon mitigation strategies should be considered for more effective and lasting results. [Publication date: July 12, 2022]

Can improved airflow help decrease radon levels in your home? Yes, it can. When you open windows, doors, and vents on the lower floors of your house, you enhance the overall ventilation. This boost in ventilation facilitates the mixing of fresh outdoor air with the indoor air, which may contain elevated levels of radon gas. As a result, the increased circulation of outdoor air can lead to a reduction in radon concentration, making your home a safer environment.
