Q: Why is radon detection important for residential properties?

• <div><p>Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.</p></div>

Q: Do air purifiers help with radon?

• <div><p>No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.</p></div>

Q: How long does radon mitigation take?

• <div><p>Installation typically takes 1-2 days, depending on the system and property layout.</p></div>

Q: What is considered a safe or dangerous level of radon?

• <div><p>No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.</p></div>
