Radon Mitigation Systems

How it Reduces Indoor Radon Levels

The most common form of Radon Mitigation are fans. The fans ventilate the home or building, and use a suction-like air pressure to pull the air from under the building’s foundation. The pipes then transport this air to above the building, which quickly dilutes the toxins so the air isn’t as dangerous to breathe. This type of mitigation system is called sub-slab depressurization, active soil depressurization, or soil suction. Typically Radon gas can be reduced through this technique, which is easy for the homeowner and keeps the house or building safe. Ventilation systems can use a heat exchanger, or energy recovery ventilator, to recover part of the energy that may be lost in the process of exchanging air with the outside.

Radon gas mitigation from water may happen at a treatment plant, entry point, or point of use. The public water in the United States used to be instructed to treat the Radon gas, however, private wells are not regulated. The Radon gas can be encapsulated with granular activated charcoal, or the water can be aerated and release the radon through that. Aeration systems move the Radon gas from the water into the air, which is then quickly diluted and safe to breathe.

Radon mitigation systems are specific to where the Radon is located, how high the levels are, and the house or building that is in danger. Mitigation systems are not one size fits all. It will require the help of a mitigation professional to assess the needs of the house or building for mitigation to be successful. There are different kinds of mitigation systems, and the technician who works with the installation will be informed of what one to create.

The first is an exterior installed Radon mitigation system. The pressurized components of the mitigation system are located on the outside of the house, and the interior components are under the suction. The Radon vent stack will rise above the top of the home or building. This is where the Radon gas is diluted and safe to breathe. The suction pipes are installed in the lowest level of the home or building, with the soil below the pipes. The pipes continue up the building’s foundation, carrying the contaminated air to the top of the building.

Another mitigation system comes in the form of installation in the attic. With these mitigation systems, they are installed through the attic space. The mitigation system is then hidden from everyday viewing. These mitigation systems are great for homeowners in cold, snowy climates, since they offer better protection from the elements. Most attic installations use garages to house the pipes.

Passive Radon mitigation systems would be used in new homes, and most frequently sought by real estate professionals. These mitigation systems should seal cracks and sumps in concreate slabs and foundations. These passive mitigation systems create a vacuum that makes the suction aspect in the pipes work, to pull the Radon gas out to the top of the house.
