Radon exposure is most clearly associated with which health effect?

• A. Lung cancer
• B. Asthma
• C. Seizures
• D. Skin cancer

Answer: (A)

Radon exposure is most clearly linked to lung cancer. Radon is a radioactive gas that can accumulate indoors. Its decay products emit alpha particles when inhaled, which damage the cells lining the lungs over time. A large body of research, including studies of residential exposure and miners, shows that higher radon levels and longer exposure increase lung cancer risk. The effect is present in both smokers and non-smokers, though smoking greatly amplifies the overall risk due to a synergistic effect. Other health effects like asthma, seizures, or skin cancer do not have as strong or direct a link to radon exposure based on the evidence we rely on, which is why lung cancer is the health outcome most clearly associated with radon.
