We’re all familiar with the U.S. Surgeon General’s warning on the hazards of cigarettes. But what many don’t know is that the Surgeon General also warns against a substance that is the second-leading cause of lung cancer, can be present in any home or building, is especially prevalent in Iowa and may be presenting a health risk to your family right now. That substance is radon.
Radon is a colorless, odorless and tasteless gas that comes from the breakdown of naturally occurring uranium in the soil. Radon can enter homes through cracks in the foundation and other pathways. Any home can have radon, regardless of age or foundation type. High-rise apartments, commercial building and schools can also have high radon levels.
