The Clark County Health Department (CCHD), along with the Wisconsin Department of Health Services (DHS) and the U.S. Environmental Protection Agency (EPA), recommends that all residents test their homes at least once for the presence of radon gas. If a high level of radon gas is detected, simple steps can be taken to correct the problem.

What is Radon?
Radon is a naturally occurring radioactive gas that originates from the decay of uranium found in rocks, soil, and water. It is expelled from the ground and can enter homes through cracks in the foundation, openings around joints and pipes, and dirt floors. About 1 out of 10 Wisconsin homes has high radon levels; however, the amount of radon gas varies across the state. An interactive map displaying the average radon levels based on zip codes throughout the entire state can be found on

The only way to know if you have a safe level of radon inside your home is to conduct a radon test. Testing is simple, quick, and inexpensive. Short-term radon test kits provided by the Clark County Health Department are available for $10.00 and can be picked up at the Health Department. Kits can be mailed for an additional $2.00. Radon test kits can also be found at many local hardware stores. To purchase a kit from CCHD or for more information, please call 715-743-5112.
