Radon is a colorless, odorless radioactive gas present in the soil. Radon can lead to lung cancer when it gets into buildings where we breathe the radon and it's radioactive decay products.

Radon is undetectable except through specific testing. Every home in Iowa should be tested for radon. Most people start the testing process by using a do-it-yourself radon test kit. Testing for real estate transactions is a little different, call for information 1-800-206-7818.
