Home Entry

Radon gas enters the home through openings to ground.

  • Floor/Wall Cracks
  • Floor/Wall Joints
  • Pump/Drain Openings
  • Utility Entrance Points

In winter months, the effect of heat rising in the home, called the "stacking effect", causes an elevated level of radon gas to enter through openings to ground. In the radon decay cycle a gas becomes a metal, first to Po218 and later to Po214 . These metals decay further, giving off α in the process. Prolonged exposure to elevated levels of radon gas may lead to lung cancer.
