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.

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

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.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional.
