How Radon is Reduced – Rochester, Minnesota
How Radon is Reduced in Rochester, Minnesota
If you’ve discovered that your Rochester home has abnormally high levels of radon, reducing the amount of the gas in the air is vital to protecting the health of your family. The U.S. Environmental Protection Agency (EPA) recommends that Rochester homeowners use mitigation systems that prevent radon from ever entering their homes.
The most common method for radon mitigation in Rochester is the soil suction technique. This method is effective because much of the radon in the Rochester area is due to the breakdown of uranium in the ground. The soil suction technique uses a vent fan to pull the radon downward under the house. The radon then travels through one or more pipes until it reaches the open air above your home, where it mixes with the atmosphere and no longer poses a threat.
Several systems are available for soil suction radon mitigation. The type that is right for your Rochester home depends mainly upon its foundation type. In addition, the presence of a sump pump can also influence the placement of the components for soil suction mitigation devices in houses located in Rochester.
The benefit of soil suction radon mitigation systems is that they require only minimal modifications to your existing home. An efficient system can have a profound effect upon radon levels in Rochester homes. In fact, the Minnesota Department of Health reports that many systems can reduce radon levels to 2.0 picoCuries per Liter. This represents a significant reduction as the EPA uses 4.0 picoCuries as the guideline for when radon mitigation typically becomes necessary.
Radon Entry Points
Cracks in concrete blocks and foundations also contribute to the presence of radon in homes and occur primarily due to moisture and temperature changes. Unfortunately, Rochester’s humid continental climate makes cracks common; the city receives an average of 30 inches of rainfall and 48 inches of snowfall per year with average high temperatures of 21 degrees Fahrenheit in January and 82 degrees Fahrenheit in July.
Repairing cracks in concrete, spaces in brick veneers and loose pipe fittings all contribute to mitigating the amount of radon in Rochester homes; however, the EPA does not recommend these home repairs as the sole method of radon mitigation. Rather, Rochester homeowners should make these home improvements to complement soil suction systems or other radon mitigation techniques.
Similarly, opening windows and doors to ventilate a home is not adequate to reduce radon levels inside. Although allowing fresh air to enter the home dilutes the amount of radon present in the air you breathe, studies show that this only temporarily improves air quality. Radon levels typically return to their former levels within 12 hours of the house being closed up.
Because many factors contribute to the best design for a radon mitigation system in your Rochester home, you should enlist the help of a professional. A qualified radon contractor can help you determine what method of radon mitigation is ideal for your home.
