What is the key purpose of using active soil depressurization in radon mitigation?

The key purpose of using active soil depressurization in radon mitigation is to effectively reduce radon levels indoors. This method functions by creating a pressure differential that prevents radon gas from entering a building from the soil beneath it. By actively pulling air from the subsurface and venting it outside, the system lowers the concentration of radon in the soil adjacent to the foundation. This ensures that less radon gas seeps into the living spaces, thereby significantly lowering indoor radon levels.

While increasing the indoor temperature, enhancing air quality, and removing moisture may have certain benefits, they are not the primary objectives of active soil depressurization. The main focus of this technique is on managing radon gas, which is a potent health risk.
