Radon Detection and Reduction questions, answered by experts

You should have a professional test for radon every two to five years. A good rule of thumb is to get testing done every five years if you’ve never had an issue before and every two years if you have. You may also want to schedule testing if you notice symptoms of radon exposure or if you do intermittent DIY radon testing and notice changes in your levels between tests. If you have an active radon monitor, you can schedule testing if you notice levels increasing over time.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

The short answer is no, air purifiers do not help with radon. While they certainly can improve the air quality of your home, they only clean pollutants from the air. Radon is radioactive, and it isn’t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

DIY radon detection is possible using over-the-counter test kits, but professional testing can provide more accurate assessments, especially in cases of high initial readings.
