What is a potential consequence of high radiation exposure?

High radiation exposure can lead to the development of cancer, which is a well-documented consequence of excessive ionizing radiation. When radiation interacts with cells in the body, it can cause damage to the DNA within those cells. If this damage is not properly repaired, it can lead to mutations that may result in uncontrolled cell growth, ultimately forming tumors. This is particularly concerning because different types of cancer can develop depending on the specific cells that are affected by the radiation.

The other choices suggest positive outcomes, such as improved immune function, increased physical strength and endurance, and enhanced cognitive abilities. However, these outcomes are not associated with high radiation exposure. In fact, radiation can harm immune function, diminish physical health, and negatively impact cognitive abilities, making these other options inaccurate in the context of high radiation exposure.
