![]() No level of radiation is considered completely safe, but as it cannot be totally eliminated, governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced. There is no proven link between radon in water and gastrointestinal cancers, however, extremely high radon concentrations in water can be aerosolized by faucets and shower heads and contribute to high indoor radon levels in the air.įluctuation of ambient air radon concentration over one week, measured in a laboratory ![]() Treatment systems using aeration or activated charcoal are available to remove radon from domestic water supplies. In particularly troublesome dwellings, air exchangers can be used to reduce indoor radon concentrations. Concrete slabs, sub-floors, and/or crawlspaces are sealed, an air pathway is then created to exhaust radon above the roof-line, and a radon mitigation fan is installed to run permanently. Mitigation of radon in the air by active soil depressurization is most effective. Radon is a significant contributor to environmental radioactivity and can cause serious health problems such as lung cancer. Radon mitigation is any process used to reduce radon gas concentrations in the breathing zones of occupied buildings, or radon from water supplies.
