Carole is a 60-year-old Caucasian housewife born and raised in Des Moines, Iowa, who presents to her primary care clinic with concerns regarding shortness of breath. She undergoes a chest X-ray and is told that she has lung cancer. Lung cancer is the leading cause of cancer death among nonsmokers in the United States. When she asked why she might have developed lung cancer since she never smoked, she is told radon is responsible for about 21,000 lung cancer deaths every year. Radon is a tasteless, odorless, invisible radioactive gas that is estimated to cause thousands of cancer deaths each year. Radon in soil and water enters homes through cracks and gaps in a home's foundation, floor, and walls.
