Radon Detection and Reduction questions, answered by experts

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

No level of radon is technically safe, but because it’s everywhere—even in the air outside—it’s impossible to avoid entirely. Instead, the Environmental Protection Agency encourages taking preventative measures if the levels of radon in your home rise above 2 pCi/L. (For reference, the average radon level in homes across the United States is 1.3 pCi/L.

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