Radon Mitigation is the technique used for the removal of the radon gas from the soil before it decays (uranium) in to the air particles of the structure. Different techniques are used for this purpose but one of them is most effective i.e. it is cost efficient as well as effective. This technique is known as active soil depressurization. In this technique a slab is used to seal the cellar floor and then vacuum is generated with the help of a special radon mitigation fan. This fan then sucks the Radon Gas before it enters the structure and release it above the roofline. Radon Mitigation is done because Radon sticks with the air particles and when inhaled they goes in the lungs and causes lung cancer. So, Active Soil depressurization is used to remove radon gas in high concentrations before it enters in the building and causes the inside air to get polluted.

Active Soil Depressurization System Explained
- A sub-slab depressurization system is very common way of removing radon gas from homes and building and this is mostly preferred as well because it is cost efficient and somewhat effective. In this method a radon mitigation technician digs a hole underneath the sealed floor and creates a pit and above this a radon mitigation fan is installed which creates a negative pressure (vacuum) underneath to remove radon gas. In Older Homes this technique is used because they don’t have a sump pump or any such things like that of radon mitigation fans installed for removing radon gas. In modern homes when they are built then sump pumps are installed during the construction so as to remove radon gas from underneath if it is present. Radon mitigation Fans by creating a vacuum sucks the radon gas and moisture from the soil as it is continuously running so it sucks moisture and makes soil dry which creates cracks and cervices in them and this will further suck the radon gas from within the cracks and ultimately more gas is released which is stuck in them. And all this gas and moisture will be collected in the pit and then from there removed by the radon mitigation fan in to the air above the floor. Basically, a sub-slab depressurization system is known for its moisture removal performance.
- Drain-Tile Depressurization System is another method of radon mitigation. This is much effective system as compared to that of sub-slab depressurization system because it is laid under the whole basement floor in the form of a drain pipe and at the exit the radon mitigation fan is installed to remove the soil gas. This is effective in a sense that as we know that radon mitigation fan removes radon gas from a place of low resistance so drain-slab will gather the radon gas from different places and collect it to the collection pit so because of this our radon mitigation fan doesn’t have to work so hard for sucking gas as that in sub-slab system. So, this method is rather considered effective as compared to sub-slab system.
