Approximately how many radon-related cancer deaths occur annually?

The correct option indicates that approximately 15,000 to 20,000 radon-related cancer deaths occur annually. This figure is derived from research conducted by health organizations, including the Environmental Protection Agency (EPA) and the World Health Organization (WHO), which have assessed the impact of radon exposure on public health.

Radon is recognized as the second leading cause of lung cancer after smoking. Each year, thousands of people develop lung cancer due to prolonged exposure to radon, which is a naturally occurring radioactive gas found in soil and rock. The understanding of these statistics emphasizes the importance of radon testing and mitigation in homes, especially in areas known to have higher levels of radon concentration.

The estimate of 15,000 to 20,000 deaths serves as a crucial reminder of the potential health risks associated with radon exposure, illustrating the need for continuous awareness and action to minimize its impact, especially in residential environments.
