As colder weather settles in, it’s a good time to check your home for radon. Radon is a gas that comes from the ground and can build up indoors. You can’t see or smell it. Breathing high levels over time can cause lung cancer, and a test is the only way to find out how much radon is in your home.
Find a low cost test kit
The Southeastern Wisconsin Radon Information Center serves Milwaukee County residents. Call (262) 896 8300 to order a basic kit for $10. The price includes lab analysis. You’ll need postage to send the used kit to the lab. Kits are also available at hardware stores. Check the package to see whether it includes the lab fee.
Pick a spot where people spend time
The Milwaukee Health Department recommends testing on the lowest floor where people regularly spend time. If you use your basement as a living room or home office, that’s a place to consider. Avoid kitchens, bathrooms and direct sunlight. Follow the directions in your kit for where to put it, exactly when to start and stop the test, and where to send it.
A basic test usually takes two to four days. Wisconsin health officials say winter is a good time to test because it’s easier to keep windows closed. For a basic test, the state recommends closing windows and outside doors at least 12 hours before you start. You can still come and go as usual.
Ask what to do if the result is high
If your first result is 4 picocuries per liter or higher, call the regional center for help choosing a second test. If you rent, share the result with your landlord and discuss next steps. The City of Milwaukee also answers general radon questions at (414) 286 6800.
