Did you know 7 out of 10 Iowa homes have high levels of radon? Radon is a gas that you can’t see, smell or taste, but it can be dangerous! In fact, it’s the second leading cause of lung cancer in the United States right behind cigarette smoking.
You’ll likely see promotional material and social media posts about radon during the winter because it’s the best time of year to test your home for radon. In the winter, since windows and doors are closed up, radon levels can build up. It takes years for people exposed to have symptoms, so the best preventer is to have your home tested.
Test kits can usually be obtained from your county health department. The test involves setting a box in the home anywhere from a few days to a month and then sending it into a lab. Homes in Iowa that are purchased during real estate transactions are required to test for radon now because of the prevalence in Iowa. However, homes that are owner-occupied or rentals are not required to test for radon at this time. Your test results will indicate if any additional measures need to be taken.
