Because there is a lot of risk of having radon gas present in buildings in the US, it has become a cause for concern for many homeowners and others who own buildings in the US, especially as the risks associated with inhaling the gas are many including being the fact that this gas is the second most important cause of lung cancer, after cigarette smoking. The need to select a proper solution with regard to radon mitigation systems is indeed high, especially if your building or home is located in a high risk area.
In fact, in some areas, before purchasing property, it is necessary to have a specific test performed to ensure that the building is free from radon gas. You have a number of choices with regard to choosing proper radon mitigations systems including having venting pipes to the exterior of the building in order to expel the gas from the building and this form of radon mitigation system is known as Passive mitigation system.
However, when even this radon mitigation system proves ineffective, and there is still noticeable gas in the home, then you need to choose another option which is the active radon mitigation system that requires installation of a fan that runs through the building and which will create low pressure under the slabs and thus increases the rate at which Radon gas is evacuated.
In this form of radon mitigation, you may need to place the fan in a place such as an attic, which is especially necessary if the foundation of the building is slab-on-grade type or even crawl-space. In addition, you should remember that it is necessary to ensure that the vent that runs through your building’s roof does not let water from the pipe drip down onto the slab underneath because it would prove to be harmful.
The cost of installing passive radon mitigation systems would be around one hundred and fifty dollars to three hundred dollars, while that of an active system would be about two hundred and fifty dollars to five hundred and fifty dollars more, though costs will ultimately depend on how big or small is the building.
