How can radiation exposure impact human health?

Radiation exposure can significantly impact human health, particularly by increasing the risk of cancer and potentially causing radiation sickness. When individuals are exposed to high levels of radiation, it can lead to damage at the cellular level, particularly affecting DNA. This DNA damage can result in mutations that, over time, may lead to the development of cancer, as the body’s natural repair mechanisms may not always correct these errors effectively.

In addition to the increased cancer risk, high doses of radiation can cause acute health effects, known as radiation sickness. Symptoms can include nausea, vomiting, fatigue, and more severe consequences depending on the radiation dose. As such, understanding the dangers associated with radiation exposure is crucial for monitoring health risks and implementing proper safety measures in environments where radiation is present. The choice indicating that radiation has no significant health effects or enhances the immune system does not align with the established scientific consensus regarding the risks associated with radiation exposure.
