What is the purpose of testing for radon in a home?

Testing for radon in a home is crucial primarily to assess potential health risks associated with exposure to this radioactive gas. Radon is a naturally occurring gas that can accumulate in homes, particularly in lower levels like basements. It's colorless, odorless, and tasteless, making it undetectable without proper testing. Long-term exposure to high levels of radon is linked to lung cancer, making awareness and testing vital for health protection.

While other options address important aspects of home assessment and maintenance, they do not pertain to radon. Energy efficiency levels, structural integrity, and indoor humidity concern other safety and comfort factors but do not relate to the specific hazards posed by radon. Thus, the primary reason for conducting radon testing is to identify the potential health risks it poses, enabling homeowners to take necessary action if harmful levels are found.
