One of the things that threaten many American households today is the intrusion of radon gas into the home. Radon gas is the result of radioactive material underground decomposing and as that occurs, the gas due to its natural properties eventually rises up to the surface. The issue here is that many American homes are built right on top of this radioactive material and the radon gas that rises up eventually intrudes into the home through the small cracks and crevices at the base of the home. What many fail to know is that the inhalation of radon gas is actually the second leading cause to lung problems next to smoking.
Radon gas has been a problem for households for quite some time and removing the problem from the actual source itself can take a lot of effort and money. The solution to radon intrusion is by lowering the levels of the gas in the house down to a safe level in a process known as Radon Mitigation. To mitigate radon, a radon mitigation system is installed into the house. Let’s take a look at examples of these systems.
1.) Exterior Mitigation System – In exterior systems, most of the parts and components are set up outside the residence. This includes the pressurized components. Only the interior components like the fan and part of the pipes are found in the interior. The pipes connect the fan underneath to the eave top of the house allowing radon gas to be successfully vented up there. Most often the system’s fans are installed at a knee height level and opposite to the joists.
2.) Attic Mitigation System – This type of Radon Mitigation system is set up in the attic as the name suggests. Because it is set up in that area, it will be protected from the elements such as rain and snow. In addition, the look of the house will not be affected by the appearance of the metal parts and components since they are all indoors. The pipes of this system run through the garage and closets up to the attic.
3.) Passive Mitigation System – Passive radon mitigation systems is a feature that has been added to newly built houses these days. What makes this type of system great is that it requires no energy to function and relies on the structure of the house to vent the radon. Upon construction, a layer of gravel is placed which helps prevent radon from rising up further. Just under the gravel, pipes are installed which uses the natural slack effect to vent the rising gas outside the house.
4.) Crawlspace Mitigation System – Crawlspaces in houses are areas that are very susceptible to radon infiltration making the entire house vulnerable. Homes that do have crawlspaces will be most suited for this approach of mitigating radon. Firstly, a vapor barrier is set up inside the crawlspace itself which will prevent the radon from getting in the house further. Once the barrier has been set up, either an attic system or an exterior Radon Mitigation system can be set up to remove the gas.
