Air Exchangers
If the crawl spaces are inaccessible, you can’t possibly employ the Sub-Membrane Depressurization technique. You’ll need to make use of the Energy or Heat Recovery Ventilator (ERV or HRV), or simply, air-to-air heat exchangers. If the radon levels in your home are below 12pCi/L, the air exchangers can effectively help mitigate radon from the air inside your home.
The air exchangers exchange the air present inside your home with the air outside. The system uses two separate sets of flexible ducts. One set of ducts blows air from outside inside your home, and the other set blows the air inside your home outside. The air coming inside your home is slightly tempered to prevent the energy penalty. The process through which radon mitigating is done is the dilution of radon the air, but introducing air from outdoors inside your home that contains an average of 0.4 pCi/L.
Sealing the Openings
Sealing all the possible openings, including the cracks and holes, is done simultaneously with other radon mitigation techniques. It’s done to prevent the loss of the vacuum pressure that’s created around the vent pipe during the radon mitigation procedures mentioned above.
Radon Vent Fans
These fans are specialized devices that don’t allow the radon gas flowing through the system to escape. These fans are fitted to minimize the difference in the pressure and dynamics of the airflow. It is needed to achieve the target radon levels. They’re installed along with suction pipes to vent the radon-contaminated air out of the home and achieve lower radon levels in your home.
Closing Word
You need to get rid of the radon in the air inside your home on priority. There is no way you can know if the indoor air contains radon except to get the indoor air tested. Therefore, you should make radon testing a part of your regular home-care routine. If radon is detected, no matter how low the amounts are, you need to look for a reliable air quality professional to address the issue effectively.
