What is the long-term risk associated with exposure to Radon?

Long-term exposure to radon is primarily associated with an increased risk of lung cancer. Radon is a colorless, odorless gas that originates from the natural breakdown of uranium in soil and rock. When radon gas is inhaled, radioactive particles can become trapped in the lungs. Over time, the radiation emitted by these particles can damage lung tissue and lead to the development of lung cancer.

Research has demonstrated that radon is the second leading cause of lung cancer after tobacco smoking. The risk is significantly heightened in smokers due to the synergistic effect of smoking combined with radon exposure. Thus, the primary long-term health risk linked to radon exposure is the development of lung cancer, making it critical to monitor and mitigate radon levels in homes and buildings to protect occupants' health.
