How does Radon enter your home or workspace?
Air pressure inside your home is usually lower than in the soil surrounding the foundation. This difference in pressure draws air and other gases, including radon, from the soil into your home. Radon can enter an home any lace it finds an opening where the house contacts the soil: cracks in foundation walls and in floor slabs, construction joints, gaps around service pipes, support posts, window casements, floor drains, sump or cavities inside walls.
Radon can also be found in groundwater from private or small community wells. Radon produced in the ground can dissolve and accumulate in water from underground sources such as wells. When water containing radon is agitated during daily household use, showering, clothes washing or cooking, the radon gas could be released into the air. Research has shown that drinking water which contains radon is far less harmful than breathing the gas. The health risk does not come from consuming the radon, but from inhaling the gas.
