How does radon get into your home?
Radon is a radioactive gas that is created during the natural decay of uranium that is found in nearly all soils. The radon gas moves up through the ground and mixes with the air above then the radon typically enters your home through gaps, cracks and other holes in the foundation such as: cracks in solid floors, constructions joints, cracks in walls, gaps in suspended floors, gaps around service pipes and cavities in walls. As the radon moves upwards it gets diluted with outside air which enters the home through cracks, openings (doors and windows) and other penetrations. This means that the highest levels of radon are typically found in the lowest occupied portion of the home.
The amount of radon to which you may be exposed is directly related to several things:
- Where in the home you spend the majority of your time.
- How much fresh outside air typically enters the home during the day.
- Seasonal habits such as open windows, use of fans, evaporative coolers, etc.
Pillar to Post uses professional radon monitoring devices which have been classified as a “Continuous Radon Monitor” testing devices which have been evaluated and accepted by the US Environmental Protection Agency (EPA). The unit must be in place for a minimum of 48 hours.
My next post will discuss the different testing methods available.
