Radon Mitigation is the method for the removal of radon gas from the soil before it decays in to the air and make it polluted. There are different types of Radon Mitigation Systems but one of them beats the other in every way possible i.e. it is cost effective as well as effective. This method is known as active soil depressurization. In this method a slab is used to seal the cellar floor and then negative pressure is generated with the help of a special radon mitigation fans. These fans then draw the Radon Gas from the soil and release it above the floor according to the EPA standards before it enters the structure. Radon Mitigation is done because Radon sticks with the air particles and when inhaled they goes in the lungs and causes lung cancer and also there is no way to find out that whether you are exposed or not and when symptoms appeared than you’ll be at the last stage of lung cancer. So, In Active Soil Depressurization System we remove radon gas in vast amount before it enters in the building and saves the inside air from getting polluted by letting radon gas to stick with the air particles.
Types of Active Soil Depressurization System
- A sub-slab depressurization system is very common way of removing radon gas from homes and building and it is mostly preferred as well. In this method a radon mitigation technician digs a hole underneath the sealed floor and creates a collection point and above this a radon mitigation fan is installed which creates vacuum underneath to remove radon gas. In Older Homes this technique is preferred because they don’t have a sump pump or any suction mechanism 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 create a vacuum and sucks the radon gas and moisture from the soil as they are continuously running so they keep on sucking moisture and making soil dry which further creates cracks and cervices in soil bed and this will cause more radon gas to release from the cracks and get collected at the collection points. This is then removed by Radon Mitigation Fan System. Basically, a sub-slab depressurization system is known for its moisture removal rather than its radon gas removal.
- Drain-Tile Depressurization System is another method of radon mitigation system. This is much effective system and rather a bit expensive as compared to that of sub-slab depressurization system because in this a pipe like structure is laid under the whole basement floor and at the outlet of pipe 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 point for removal so because of this our radon mitigation fan doesn’t have to work hard as that they do in sub-slab system.
