Radon is a colorless and odorless gas that comes from the soil. The gas can accumulate in the home. Radon gas decays into fine particles that are radioactive. When inhaled, these fine particles can damage the lungs. Exposure to radon over a long period of time can lead to lung cancer. It is estimated that 21,000 people die each year in the United States from lung cancer due to radon exposure. A radon test is the only way to know how much radon is in your home. Radon can be reduced with a mitigation system. The Mn Department of Health has more information on radon.
Radon is produced from the natural decay of uranium and radium, found in rocks and soil. Uranium breaks down to radium, and radium eventually decays into the gas radon. Radon gas is in the soil and common throughout Minnesota. Because soil is porous, radon moves up from the soil and into the home. It can then accumulate in the air and become a health concern.
