What is a potential result of failing to address high radon levels in a home?

Failing to address high radon levels in a home can lead to long-term health risks, which is the reason this choice is correct. Radon is a colorless, odorless gas that can accumulate in homes, particularly in basements and lower levels. Prolonged exposure to elevated radon levels is associated with an increased risk of lung cancer, making it a significant health concern. The World Health Organization and other health organizations classify radon as a carcinogen, emphasizing the importance of mitigative actions when high levels are detected.

Understanding the health implications is critical, as the long-term consequences of neglecting radon mitigation can result in serious health problems for occupants. The risks are cumulative, meaning the longer individuals are exposed to high levels of radon, the greater the chances of developing lung cancer.

While increased ventilation costs, decreased property value, and higher energy bills may be relevant factors when discussing radon issues, they do not focus on the most critical impact, which is the health risk posed to individuals living in a radon-affected environment. Addressing radon levels is primarily about safeguarding health, making the long-term health risks the most compelling reason to take immediate action.
