Which statement regarding radon is false?

The correct answer indicates that radon is not a gas formed from poor furnace maintenance, highlighting a fundamental aspect of how radon is actually generated. Radon is a naturally occurring gas that results from the radioactive decay of uranium found in soil, rock, and water. It typically enters buildings through cracks in floors, walls, construction joints, and gaps around service pipes.

Understanding that radon is linked to uranium decay rather than being a byproduct of furnace maintenance emphasizes the importance of environmental factors over mechanical ones in terms of radon presence. Therefore, awareness about radon's origin can guide homeowners to focus more on monitoring and mitigating radon levels stemming from the ground rather than associating it with indoor heating systems.
