Radon is in the ground naturally but can enter your home through cracks in the walls or foundation, as well as through groundwater.

Radon Testing:
Health Risk for the Watertown Area

Radon is a radioactive gas that you can not 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


It's important to remember that no level of radon is safe. The recommended action levels are merely guidelines by which the W.H.O. and E.P.A. suggest that homeowners take measures to reduce the levels within their home.

Codington County has an especially high concentration of radon, with an average measurement of 7.4 Pci/L. An EPA-approved radon test is the only way to determine your home's radon level.
