Which of the following is a consequence of Radon exposure?

Radon exposure is primarily classified as a significant risk factor for lung cancer, which is linked to its radioactive properties. When radon gas is inhaled, it can decay into radioactive particles that can lodge in the lung tissue. This process may lead to cellular damage, specifically through alterations in DNA. The damage to DNA is a critical factor because it can result in mutations that contribute to the development of cancer over time, particularly in heavy smokers or individuals exposed to high levels of radon over extended periods.

The other options, while they may pertain to various health issues, are not associated with the specific risks linked to radon exposure. Increased skin sensitivity and ear infections are unrelated to the effects of radon. Nausea and vomiting are more typically related to other health issues, such as gastrointestinal problems or acute radiation syndrome from high doses of radiation, rather than exposure to radon, which primarily affects the respiratory system. Understanding this connection reinforces the significance of radon testing and mitigation in homes and buildings to minimize health risks.
