The Four Different Kinds of Radon Mitigation Systems

The threat of radon gas entering our household is not uncommon here in the United States. Many residential properties sit atop chunks of radioactive material that when decomposes, turns into deadly radon gas. When inhaled, radon gas can cause problems to the lungs. Although it is very hard to solve the problem right down to its very source, there is a solution which can help radon-plagued homes and that is in the form of Radon Mitigation.

Radon Reduction Systems

The idea of radon mitigation is reducing the amount or level of radon gas which has infiltrated into the house from underground and through the crevices at the base of the home. To help mitigate radon, a radon mitigation system is installed into the house which will help remove the gas from inside the home. Once it has been determined that there is a high level of radon in the house, then will it be viable to install the mitigation system.

There are different types of radon mitigation systems and determining which type of system is fit for the home will depend on certain factors which only professionals like radon mitigation contractors can assess. Today, we are going to look into the four different kinds of radon mitigation systems.

1.) Exterior – In this type of system, the parts along with the pressurized components are placed outside the residence. The components specified for interior use are set up underneath the suction area. Usually the system’s fan is attached opposite to the rim joists and kept at about one to two feet high. The system’s pipes go out at the side of the house just above the fan. These pipes connect to the eve where the radon is expelled.

2.) Attic – As the name suggests, this kind of Radon Mitigation system is placed in the attic of the house. For homes that do have attics, this would be a viable option. Because the system is placed in the attic, the homeowner won’t have to worry about any parts visible outside affecting the look of the house. Its position also grants it protection from the elements. The lines of this system usually go through the garage or through utility areas.

3.) Passive – This type of mitigation system does not require the use of energy but integrating it into the house has to be done upon the construction of the residence. The passive system features a gravel layer which will reduce the intrusion of radon. Underneath this layer of gravel, there is a pipe which will vent out the gas through the natural stack effect which is why it does not need to use any energy.

4.) Crawlspace – In houses that have a crawlspace area, this is the most viable kind of Radon Mitigation system to use. Houses that have a crawlspace are more prone to radon intrusion because this area easily lets radon in. A crawlspace radon mitigation system makes use of a vapor barrier to prevent further rising of the gas. Along with that, other parts and components may be installed to remove the gas.
