• Radon is a radioactive gas that is released during the normal decay of the elements uranium, thorium, and radium primarily found in rocks and soil.
  • Radioactive particles from radon can damage cells that line the lungs and lead to lung cancer.
  • Radon is the second leading cause of lung cancer in the United States and is associated with 15,000 to 22,000 lung cancer deaths each year.
  • Testing is the only way to know if your home has high radon levels. Wisconsin health authorities recommend radon testing and encourage corrective actions when necessary


Radon gas is naturally occuring as a result of decaying uranium deep in the earth. It rises to the earths surface where it mixes with the atmosphere. If allowed to mix and dilute it is no longer a danger.

Radon seeps into confined spaces like a home through the foundation, drain tiles, sump wells or other entry points. Once radon enters a home, it continues it's decaying process into radiation that can easily be inhaled. Like cigarettes, when breathing radon over a long period of time, irreversable damage to the lungs can happen. It is like receiving a chest xray day after day for years.

Radon is found in varying concentrations. Wisconsin has significant concentrations of radon. The map illustrates the percentages of homes that exceed the threshold of 4 picocuries per liter of air as established by the US EPA.

Radon testing is easy and inexpensive. Inspections by a certified inspector can be completed from test-set to analysis in as little as 3 days.

Radon In The News:

Feb 2, 2021 —  The World Health Organization states "Radon is estimated to cause between 3% to 14% of all lung cancers in a country, depending on the national average radon level and smoking prevalence."

WASHINGTON (January 6, 2021) — This week marks the beginning of National Radon Action Month. Every January, the U.S. Environmental Protection Agency (EPA) urges everyone across the United States to test their homes for radon gas. Radon is a naturally occurring radioactive gas that can seep into homes from the ground and, in some cases, well water supply.

“Radon is the second leading cause of lung cancer in the United States, and is both colorless and odorless, so I encourage everyone to take time this January to test and prevent radon exposure in your homes,” said EPA Administrator Andrew Wheeler. “Millions of homes have been tested for radon and repaired, but millions more homes with high levels of this radioactive gas remain.”

November 12, 2020 - Kenosha, Wisconsin "County offers free radon test kits in exchange for food donations"

The Kenosha County Division of Health is offering free radon test kits throughout November and December to anyone who donates a nonperishable food item.

There is a limit of two kits per person. All food donations will go to local food pantries.

“This is a great opportunity to ensure your home is safe from radon and to help feed the community at the same time!” said Brad Wozniak, environmental sanitarian supervisor with the Division of Health. “It’s also a good time to think about lower-level home offices and work-from-home situations. The only way to know if you have a radon issue is to test.”

Radon is an odorless, radioactive gas that is the nation’s second leading cause of lung cancer, accounting for roughly 20,000 deaths each year.

January 8, 2020

WAUSAU (WAOW)-- Radon kills about 21,000 Americans every year and the Environmental Protection Agency is making awareness a top priority in January.

Radon is radioactive gas often found in soil, rocks, and ground water. You can't see, smell or taste it, but exposure to the gas is the leading cause of lung cancer in non-smokers.

In Wausau, over 65% of homes test higher than threshold of 4.0 pC/l establish by the EPA.

But numbers can vary drastically from house to house.

"There has been several in 200's and then right next door to one those it was 0.9 so you never know what your going to be," said Thomas DeSautel, President of The Radon Man of Wisconsin.

Radon enters the home, especially during the winter months, by heat rising in the home pulling the gas from the beneath the home.

"Therefore it could suck this radioactive atom in to your house… By sucking below the concrete with greater pressure than whats applied above the concrete, you can stop it from ever coming in," said DeSautel.

In Fond du Lac, the average radon level, based on 346 tests since 2007, is slightly above what the EPA suggests is optimum, but lower than the level the EPA would be overly concerned about.

Radon is an odorless and invisible gas that comes from radioactive breakdown of uranium in soil, rock and water. It is a natural phenomenon. The gas seeps into buildings, especially in basements and ground-level rooms. Once indoors, radon can accumulate.

 The U.S. Surgeon General says radon is the second-leading cause of lung cancer in America.

 Experts at UW-Extension tracked radon levels in the state by zip code for nine years and averaged the ratings. Residents with a rating of 2 pico Curies per liter need to reduce their radon exposure by correcting the home’s ventilation, said Diana Hammer Tscheschlok, a natural resources educator at UW-Extension.  When the rating is 4 or more, the EPA strongly recommends taking action to reduce the radon.

Radon Test Disclosure Law - As of Jan. 1, 2014 all home sellers in MN will be required at the time of offer signing, to disclose whether a radon test has been performed on the offered home. The new law is expected to give all prospective buyers the opportunity to obtain past test results or to test for high radon levels themselves.

Washington D.C. - HUD announces that all FHA insured multi-family homes will now require radon testing & mitigation. Approximately 21,000 US citizens die annually from cancer caused by radon gas.
