Radon Detection and Reduction questions, answered by experts

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.

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

DIY radon detection is possible using over-the-counter test kits, but professional testing can provide more accurate assessments, especially in cases of high initial readings.

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

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.
