Radon is a radioactive gas which comes from the decay of uranium in the ground. It is a health hazard and causes cancer in people and animals exposed to it. In the United States homeowners are advised by the [[EPA]] to test for the presense of Radon and if found to take remedial action.
Radon is most often found in Basements or crawl spaces and the remedial action is to vent the area.
