Radon is present in some degree in all soil, groundwater and air.
Most of the radon gas found in air in homes comes in through the foundation from the underlying soil, although a portion of it can also come from groundwater containing radon. Anyone concerned about reducing cancer risks from radon should begin by sampling for radon in the air in their home. L were found only in a wide north central region of the state. In other regions of the state the testing of private wells for radon is probably unnecessary. Ongoing studies will delineate the regions of concern for radon in well water more precisely.
