In most cases, a system with a vent pipe(s) and fan(s) is used to reduce radon. These "sub-slab depressurization" systems do not require major changes to your home.

RADON is a naturally occurring radioactive gas that is present in almost all rock and all soil and water.  You can’t see, smell or taste it, but radon may be in your home. According to the Environmental Protection Agency (EPA), radon is the first leading cause of lung cancer in nonsmokers and the second leading cause of lung cancer in smokers.  The amount of radon that escapes from the soil to enter the house depends on the weather, soil porosity, soil moisture, and the suction within the house.  High levels of radon can be found in any type of home, so it is important for everyone to test their home.

The EPA recommends testing your home every two years to ensure radon levels stay below EPA action level.  Environmental and/or structural changes may occur, such as home settling causing foundation cracks that could change radon levels.  This also includes mitigated homes, to ensure mitigation system continues to work properly.   The EPA also recommends retesting if you have renovated or altered your home since you last tested.

Why Is it important to "Know your level"?


According to the, Environmental Protection Agency (EPA), exposure to radon in the home is responsible for an estimated 21,000 lung cancer deaths each year.  The Iowa Radon Survey has indicated that Iowa has the largest percentage (or 71.6%) of homes above the US Environmental Protection Agency action level of 4pCi/L. It is also designated by the US EPA as an entirely zone 1 state, which means that at least 50% of the homes are above US EPA's recommended action level.  Radon is a health hazard with a simple solution.
