Which of the following can be a consequence of long-term radon exposure?

Long-term exposure to radon is significant because it has been established as a leading cause of lung cancer, particularly among non-smokers. Radon is a naturally occurring radioactive gas that can accumulate in homes, especially in lower areas like basements. When inhaled, radon decay products can damage lung tissue, leading to mutations that may develop into cancer over time. This connection has been documented through numerous studies, establishing radon as a critical health risk. Preventative measures, such as radon testing and mitigation strategies, are essential to reduce exposure and associated risks, especially in regions where radon levels are known to be high.

The other options presented do not have a direct link to radon exposure as established in scientific research.
