What is the purpose of radon fan and vent piping in the mitigation process?

The purpose of radon fan and vent piping in the mitigation process is to exhaust radon gas outdoors. In a radon mitigation system, a fan is used to draw radon that has accumulated beneath a building and then push it through a venting pipe that leads directly outside. This process effectively reduces the concentration of radon gas within the indoor air by preventing it from entering the living spaces. By directing radon gas away from the home or building, the system helps lower the potential health risks associated with long-term radon exposure.

This approach is essential because radon is a radioactive gas that can seep into homes from the ground and poses significant health risks, including lung cancer with prolonged exposure. The design of the fan and venting system is crucial for maintaining proper airflow and ensuring that any radon that is drawn from beneath the building is safely released at an appropriate height outdoors, minimizing the risk of re-entry into the building.

Other options, such as circulating air throughout the building, keeping crawl spaces dry, and filtering incoming air, do not specifically address the primary function of radon mitigation systems. These functions may be relevant to other ventilation or moisture control systems, but they do not focus on the critical goal of safely removing radon gas from the
