Radon is a gas that occurs naturally outdoors in harmless amounts. It's produced from the breakdown of uranium in soil and rocks. It sometimes gets concentrated in homes built on soil with natural uranium deposits. It can enter buildings through cracks in floors or walls, construction joints, or gaps in foundations around pipes, wires or pumps. Radon levels are usually highest in the basement or crawl space.
