How to Check If Your Radon Mitigation System is Working

Radon is an invisible, odorless, and tasteless radioactive gas that has the potential to accumulate inside your home at levels that may be harmful to you, your family, and your pets. Long-term radon exposure is the second leading cause of lung cancer, after smoking, and results in over 20,000 deaths annually. One of the best ways to keep your home healthy for all its occupants is to test regularly for radon, and if unacceptable levels of it are detected in your home, to install a mitigation system. If you already have a radon mitigation system, how do you know if it is working correctly?

The best way to tell if your system is working properly is to regularly check the system monitor. The most common type of mitigation system in Illinois is Active Sub Slab Depressurization, which doesn’t require major construction or renovation. Active systems (those utilizing a fan) have a manometer, a U-shaped tube usually mounted to the radon vent pipe in the basement or garage. The tube is filled with fluid that, if the suction created by the radon fan is working, will be higher on one side of the gauge. If the fluid levels are equal on both sides, the fan is malfunctioning. Some systems may include an indicator light or audible alarm. Passive mitigation systems won’t have a monitor because they don’t utilize a fan.

Another method is to test your radon levels a minimum of once every two years. Testing is easy and inexpensive, and you can do it yourself. You can also hire a professional mitigation company for a more detailed radon inspection report and a mitigation system inspection. It’s best to do a long-term test, or test during different seasons of the year, for the most accurate results. Don’t rely on an old test result; radon levels can change over time.
