How does radon enter a home?

Since radon is produced from soil, it is present nearly everywhere. Because soil is porous radon gas is able to move up through the dirt and rocks and into the air we breathe. If allowed to accumulate, radon becomes a health concern.

Components that Affect Radon Accumulation

Two components that affect how much radon will accumulate in a home are pathways and air pressure. These components will differ from home to home.

  1. Pathways are routes the gas uses to enter your home and found anywhere there is an opening between the home and the soil.
  2. Air pressure between your home's interior and the exterior soil is what helps to draw radon gas into the home via pathways.
