Final Answer:
Exposure to radon for extended periods significantly increases the risk of lung cancer.
Step-by-step explanation:
Radon is a naturally occurring radioactive gas that results from the decay of uranium in soil and rocks. When radon gas is released from the ground, it can accumulate in enclosed spaces, such as homes and buildings. Prolonged exposure to elevated levels of radon increases the risk of lung cancer, particularly in individuals who smoke. Radon decay products can attach to dust particles in the air, and when inhaled, these particles can deposit in the lungs, emitting radiation that can damage lung cells and contribute to the development of cancer. Mitigating radon exposure involves testing and implementing measures to reduce radon levels, such as ventilation and sealing entry points.
