Radon Information


Are you in danger from Radon?  Radon is radioactive naturally occurring gas.  It may seep into your home from the rocks below.  It is the second leading cause of lung cancer.  The Green River District Health Department has free Radon Test kits available.  Please contact your local Environmental Department to obtain a free test kit.

What is Radon?

Radon is a naturally occurring, radioactive gas that comes from the natural breakdown of uranium, in soil, rock and water. Radon gets into the air you breath through cracks, crevices and openings in the foundation. Radon gas is not visible and has no odor or taste.

Nearly one in fifteen homes in the U.S. has elevated radon levels. Testing the home is the only way to determine the radon level. Depending on the level of radon in the home, additional action may be needed. According to the EPA there is no known safe level of exposure to radon. The EPA strongly recommends immediate mitigation of the home if the test shows four picocuries (pCi/L) or more. If the radon test shows between two and four pCi/L, the owner should consider radon mitigation.
