Smoking and Radon
Radon has been proven to cause lung cancer when long term exposure to elevated levels exists; low concentrations can add up as well. If you are a smoker, the radon risk is greater than for non-smokers. The effect of smoking causes damage to the lungs hairlike cilia and mucous linings. To reduce your risk of lung cancer, stop smoking and test your home for radioactive radon gas and fix your home if levels are elevated.
