Q: Is there a safe level of radon?

• <div><p>No level of radon is technically safe, but because it&rsquo;s everywhere&mdash;even in the air outside&mdash;it&rsquo;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.</p></div>

Q: Do air purifiers remove radon?

• <div><p>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 <a href="https://www.angi.com/articles/how-to-clean-the-air-in-your-home.htm">improve your indoor air quality</a> in other ways, don't rely on it to reduce radon.</p></div>

Q: How is radon detection conducted professionally?

• <div><p>Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.</p></div>

Q: How does radon enter my home?

• <div><p>Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.</p></div>

Q: How often should I get radon testing done in my home?

• <div><p>You should have a professional test for radon every <b>two to five years</b>. A good rule of thumb is to get testing done every five years if you&rsquo;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.</p></div>
