How Radon is Reduced – Raleigh
High radon levels are a common problem for homeowners in Raleigh, North Carolina. If you’re among those facing the problem, the U.S. Environmental Protection Agency (EPA) recommends you install a mitigation system to prevent radon from ever entering your home.
Most Common Radon Reduction Method
The most common method for radon mitigation in Raleigh is the soil suction technique. This method is effective because much of the radon in the Raleigh area is due to the breakdown of uranium in the ground. The soil suction technique uses a vent fan to pull the radon downward. The gas then travels through one or more pipes until it reaches the open air above your home. There, the gas mixes with the outdoor air, where it becomes diluted and no longer poses a threat.
Several systems are available for soil suction radon mitigation. The type that is right for your Raleigh 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 Raleigh.
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 Raleigh homes. In fact, the North Carolina Department of Environment and Natural Resources reports that properly installed systems can easily reduce radon levels to below 4 picoCuries per liter, greatly lessening the risk of health problems.
Repairing cracks in concrete, spaces in brick veneers and loose pipefittings all contribute to mitigating the amount of radon in Raleigh homes; however, the EPA does not recommend these home repairs as the sole method of radon mitigation. Rather, Raleigh homeowners should make these home improvements to complement soil suction systems or other radon mitigation techniques.
Opening Windows Not a Radon Reduction Solution
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.
Drinking Water, Groundwater and Radon Contamination
Drinking water supplies are also sources of radon contamination in the Raleigh area, particularly for homes that rely on groundwater wells rather than treated public water systems. For homes with high levels of radon in their water, aeration systems are used to reduce levels of the gas. In these systems, air is passed through the water, collecting the radon gas and then venting it to the outdoors. The best aeration systems can remove 99.9 percent of radon from drinking water.
Because many factors contribute to the best design for a radon mitigation system in your Raleigh 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 you.
