Radon Detection and Reduction questions, answered by experts

Yes, DIY kits are available, but professional testing provides more accurate results and comprehensive reports.

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

It is worthwhile to get radon testing done, especially if you haven’t in the past and don’t have active radon monitoring set up in your home. According to the American Lung Association, radon is a potential issue in all states, and testing is the best way to determine if it’s a current problem in your home. Radon testing includes professional tests that determine ongoing radon levels in your property, and it usually includes a mitigation protocol to help you decide what measures to take to protect your home and household members.

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.

Testing typically costs between $150 and $500, depending on the method used and the number of areas tested.
