Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil and rock. It seeps into buildings through foundation cracks, floor joints, and service penetrations. Because it’s odorless, colorless, and invisible, it often goes undetected until it poses a significant health risk.
According to the U.S. Environmental Protection Agency (EPA), radon exposure is the second leading cause of lung cancer in the United States, responsible for more than 20,000 deaths annually. While every building has some level of radon, sustained exposure to elevated concentrations is the concern, and that risk can only be managed through consistent measurement.
