Radon Detection and Reduction questions, answered by experts

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

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.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

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.
