Stop Smoking


Radon, Smoking and Lung Cancer

People who are exposed to elevated levels of radon and smoke or are exposed to second-hand smoke, have a higher risk of developing lung cancer than people who are exposed to radon alone.

For smokers, and people exposed to second-hand smoke, the risk of lung cancer is increased due to the combined effects of radon and smoking.

For example, if you are a lifelong smoker but are not exposed to high levels of radon, your risk of getting lung cancer is one in ten. If you are also exposed to a high level of radon, your risk becomes one in three.
