Lung cancer caused by radon exposure linked to 400 deaths annually in Iowa

Radon gas is naturally occurring, invisible, odorless, and the leading cause of lung cancer in non-smokers. Nearly three-quarters of Iowa homes have tested high, and yet most Iowans have never tested their home, and many have never heard of radon. Joined by Maria Steele, retired nurse practitioner and lung cancer survivor, Dr. Richard Deming, medical director at MercyOne Richard Deming Cancer Center, and Juliann Van Liew, Polk County Health Department Director, we look at the radon problem in Iowa. We talk about what it is, why it's so pronounced in the state, what's being done about it, and how to limit exposure.
