Radon is a colorless, odorless, and tasteless radioactive gas that naturally forms from the decay of uranium in soil, rock, and water. Despite being virtually undetectable without special equipment, it is the second leading cause of lung cancer in the United States after smoking. Because it seeps into homes through cracks in foundations, gaps around service pipes, and even well water, radon testing is crucial to ensure indoor air safety.

Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil, rock, and water. It is colorless, odorless, and tasteless, making it virtually undetectable without specialized equipment. When radon gas accumulates inside homes and buildings, it can pose serious health risks. In fact, the U.S. Environmental Protection Agency (EPA) has identified radon as the second leading cause of lung cancer in the United States, second only to smoking.
