Radon Detection and Reduction questions, answered by experts

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. 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 action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Mitigation reduces radon levels, protecting your health and complying with safety standards.
