Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. 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 action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

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

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

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
