Radon Detection and Reduction questions, answered by experts

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.

A radon test has no effect on humans—only the radon in the air does. The test does not redistribute the radon that is already present so yes, it’s safe to be around the testing kit even if it isn’t safe to be in the room itself. The test absorbs and measures the radon, but doesn't absorb enough of it to make the room any safer.

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.
