Radon gas is present almost everywhere, and its concentration is higher in covered spaces like in a basement or a storage room. Radon is produced as organic materials in soil and rock decay. The gas gets suctioned into space above its source because of the air pressure difference. This pressure difference creates a suction effect pulling Radon gas into space. Most living spaces do not have enough ventilation to dissipate the gas and reduce its concentration.
Radon mitigation always starts with testing radon levels in your home. The gas concentration level will guide you as to the best Radon mitigation strategy. Radon Testing uses a device placed in the lowest level of living space. The goal of a Radon Testing is to measure the level of Radon in a living space. We cannot eliminate Radon, but the preferred Radon concentration level is below 2.0 pCi/L. Reducing the Radon gas level might be challenging without a proper mitigation system in place. However, there are some practical ways you can do to reduce the Radon level.
Proper Ventilation
Radon is a gas and its concentration increase as more of the gas gets suctioned into space. Although it is cheaper and more convenient to close space like a storage room, this prevents air circulation that helps in dissipating Radon. Substantial ventilation is key to lowering the level of Radon. In case you cannot open a window all the time, at least schedule an hour or two to have it open just to allow fresh air to circulate.
Seal the Breaks
Radon gets into space because of an opening or gap in your flooring or foundation. Try to survey your basement for any cracks or gaps and seal them with caulk or epoxy sealant.
Lower the Air Pressure Difference
Radon moves from the ground to space because of the air pressure difference. The air pressure exerted on the ground is higher compare to the spaces above. This air pressure difference creates a suction effect. The higher the difference the more Radon gas is suctioned to space. Limit the use of exhaust fans, wood stoves, and fireplaces as they can lower the air pressure inside your home. In case these appliances must be used often, try to open as many windows to allow fresh air.
