Does long-term exposure to radon increase the risk of lung cancer?

Long-term exposure to radon is recognized as a significant risk factor for lung cancer. This connection arises from the fact that radon, a naturally occurring radioactive gas, can accumulate in buildings, particularly in basements and lower levels. When inhaled, radon and its decay products can damage lung tissue, leading to an increased likelihood of developing cancer over time.

The scientific consensus, supported by extensive research, confirms that there is no safe level of radon exposure. Increased exposure correlates with a higher risk of lung cancer, making it critical for homeowners and health professionals to monitor radon levels, especially in areas known for higher natural radon concentrations. This understanding underlines the importance of radon testing and mitigation methods in homes and workplaces to reduce potential health risks.

While it is relevant to consider that exposure risks can compound with other factors, such as smoking, the foundational principle remains that long-term radon exposure itself is a significant direct contributor to lung cancer risk.
