Radon Detection and Reduction questions, answered by experts

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
