What does the EPA recommend regarding radon testing in homes?

The correct response emphasizes that the Environmental Protection Agency (EPA) recommends testing all homes for radon, regardless of the home's age or location. This guidance is grounded in the understanding that radon can be found in any home, and it poses significant health risks due to its radioactive properties and potential link to lung cancer. Since radon is a naturally occurring gas that can infiltrate homes from the ground, effective testing is crucial to ensure safety for all inhabitants.

This recommendation highlights the importance of proactive health measures. Even homes located in areas considered to have lower radon levels can have variable concentrations of the gas due to numerous factors like geology, construction materials, and home ventilation systems. Consequently, testing all homes, rather than limiting it to specific situations or demographics, helps to identify and mitigate any potential radon presence, protecting the health of residents.
