How does radon get into my house?

Air pressure inside your home is usually lower than pressure in the soil around your home's foundation. Because of this difference in pressure, your house acts like a vacuum, drawing radon in through foundation cracks and other openings like floor drains, ductwork, and pipes.

Radon may also be present in well water and can be released in the air in your home when water is used for showering and other household uses. In most cases, radon entering your home through water is a small risk compared with radon entering your home from the soil.
