Radon is a radioactive gas that you cannot see or smell. It is not able to be detected by carbon monoxide or smoke detectors. The average person receives a higher dose of radiation from radon in their home than from all other sources combined. ​

Radon forms from the decay of radioactive elements, such as uranium, found in rocks and soil throughout the world. According to the US Surgeon General, Radon is the second leading cause of lung cancer in the US.


East River South Dakota is in the Red Zone of high radon levels meaning the average home has higher than the recommended action level.
