Radon exposure is identified as the second leading cause of lung cancer in the United States. Radon is a radioactive gas that is produced from the natural decay of uranium in soil, rock, and water. It can accumulate in homes and buildings, particularly in lower levels such as basements. Prolonged exposure to radon can damage lung tissue and leads to an increased risk of lung cancer, similar to the effects of smoking.

While smoking is the leading cause of lung cancer by a considerable margin, radon exposure follows as a significant risk factor despite being less well-known. Understanding the health risks associated with radon exposure is crucial for public health, especially in areas where radon levels are higher due to geological conditions. This context illustrates the importance of testing for radon and implementing mitigation strategies in homes and buildings to protect against its harmful effects on lung health.
