ABOUT RADON


Radon is an odorless, colorless, tasteless, radioactive soil gas that is the second leading cause of lung cancer in the United States. In the United States, an estimated 22,000 people die of radon induced lung cancer annually. One person dies of radon induced lung cancer every 24 minutes. Many of these deaths can be prevented by conducting a simple test and then taking action to reduce elevated radon levels when found. The United States Environmental Protection  Agency - USEPA - estimates that 1 in 15 homes have higher than recommended radon levels.  In Minnesota 2 in 5 homes have radon levels that pose a significant health risk.


Two factors that contribute to MN high radon levels are the state geology and our climate.  Radon enters your home via the surrounding soil  on which it sits, and if allowed to accumulate, radon becomes a health concern. Radon is found in homes though out St. Louis, Lake, Carlton, and Douglas counties.  Two components that affect how much radon will accumulate in a home, are pathways and air pressure.  Pathways are routes the gas uses to enter your home and are found anywhere there is an opening between the home and the soil.  Air pressure differences between your homes interior and the exterior soil is what helps to draw radon gas into the home via these pathways.  Minnesota homes commonly operate under a negative air pressure, especially during the heating season. Meaining the air pressure inside your home is typically lower than the surrounding air and soil. This creates a vacuum that pulls soil gases, such as radon, into the home via pathways.  Other factors that contribute to air pressure changes in your home include: stack effect created from heating your house, down wind draft created by strong winds, and vacuum effect from combustion appliances in your house, like exhaust fans, hot water heaters,  and furnaces. 


TESTING


The Minnesota Department of Health along with the EPA recommends that all homeowners test their homes for radon.  Everyone at Advanced Radon Solutions couldn't agree more. With the serious heath risks that come with radon exposure testing should be on everyone's to-do list. Testing is easy and affordable and there are multiple ways to have your home tested. Give us a call today to have your home tested for radon.



Radon Mitigation System


A Radon mitigation system  is needed when a house is found to have an elevated level of radon gas of 4.0 pCi/L or higher, as recommended by MDH.  We would recommend mitigation for any levels higher than 2.0 pCi/L.   First a diagnostic testing would be preformed through out the house to accurately size the mitigation system and to determine the appropriate method of mitigation to be applied.  The most common way to mitigate a house is the installation of a Active Soil Depressurization System (ASD). An ASD radon mitigation system consists of PVC piping penetrating the slab or basement of the home and extending upwards exhausting through the roof or other practicle area. Air is drawn through the piping via a suction fan, in most cases this fan is installed in the attic or on the exterior of the house. All open cracks in the slab or basement would be sealed as well as sump pits and other pathways that radon gas could enter the home. After a mitigation system is installed additional radon testing would be preformed to make sure radon levels are at a safe level.
