Radon Detection and Reduction questions, answered by experts

To determine whether you have radon in your home, you must run a test. Radon gas has no odor or color, so you won’t notice a concentration of radon. You could purchase a DIY test at a local hardware store, but it may not deliver completely trustworthy results. The best way to test and receive accurate results is to hire a local radon detection specialist.

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

Radon is a colorless, odorless gas that can cause lung cancer; testing ensures safe indoor air quality.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

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.
