How can radiation exposure impact human health?

Radiation exposure can significantly impact human health primarily through its ability to cause cellular damage, which may lead to acute radiation sickness or an increased risk of developing cancer. When individuals are exposed to high levels of ionizing radiation, the immediate effects can include symptoms such as nausea, vomiting, and fatigue, which are indicative of acute radiation sickness. This occurs because ionizing radiation can disrupt the function of essential cellular components, leading to cell death or mutation.

Moreover, prolonged or repeated exposure to lower levels of radiation is associated with an increased risk of cancer, as the DNA damage that occurs can result in mutations that may proliferate over time. This risk is not only limited to specific types of cancer but can potentially affect various organs and systems within the body.

Understanding the potential health impacts of radiation emphasizes the importance of effective radiation protection measures to minimize exposure and safeguard human health.
