Radon is the second leading cause of lung cancer in the United States (after smoking). Scientists estimate that over 21,000 lung cancer deaths in the United States each year are related to radon. Exposure to the combination of radon gas and cigarette smoke creates a greater risk of lung cancer than exposure to either factor alone. About 1 in 15 U.S. homes is estimated to have radon levels at or above the recommended action level. Schedule your radon testing appoitment today because testing is the only way to know if your home has elevated radon levels.
