Q: What is radon and why should I test for radon?

• <div><p>What is radon? It&rsquo;s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don&rsquo;t know if it&rsquo;s seeping into your building&rsquo;s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. <a href="https://www.angi.com/articles/what-is-radon-testing.htm">Radon testing</a> measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home&rsquo;s air.</p><p></p></div>

Q: Do air purifiers help with radon?

• <div><p>The short answer is no, air purifiers do not help with radon. While they certainly can improve the <a href="https://www.angi.com/articles/how-much-does-indoor-air-quality-testing-cost.htm">air quality</a> of your home, they only clean pollutants from the air. Radon is radioactive, and it isn&rsquo;t affected by the same filtration systems that handle other airborne particles, like dust and mold. The only thing that works is a radon mitigation system.</p></div>

Q: How long does it take to see test results?

• <div><p>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&rsquo;t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. </p></div>

Q: How often should radon levels be tested to ensure safety?

• <div><p>Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.</p></div>
