(HealthDay News) -- Radon is an odorless but toxic gas that can seep into buildings, including ground-level homes.

The Environmental Protection Agency, noting that radon is found in about 1 in 15 homes, says the gas can enter a structure:

• Through cracks found in solid flooring.
• Through construction joints.
• Through cavities or cracks in the walls.
• Through gaps that form in suspended flooring.
• Through gaps around service pipes.
• Through your water supply.
