Radon gas breaks down to form radioactive elements that can be inhaled into the lungs... 2

15. Active soil depressurization (or sub-slab depressurization)
A pipe with a fan attached, is installed through the foundation floor and connected to the outside through an exterior wall or up through the roof. This system draws the radon from below the house to the outside to stop it from entering the home.
This is the most common method of radon reduction when large reductions are necessary.
Can reduce the radon concentrations in a home by over 90%.
Costs range from about $ $3000 including material and labour. There is also a small operating cost for electricity for the fan (approx. $50-$75 per year depending on the size of fan and energy rates)
Must be installed by a C-NRPP-certified Radon Mitigation Professional
