Which is a consequence of excessive radiation exposure?

Cessation of cell division is a significant consequence of excessive radiation exposure because high levels of ionizing radiation can damage the DNA within cells. When DNA is severely damaged, cells may cease to divide in an attempt to prevent the propagation of errors or mutations that could lead to cancer or other malignancies. This cessation is a protective response; however, it can also lead to tissue damage, impaired healing, and other health issues because the normal regeneration of cells is interrupted. In contrast, options related to improved cellular function, enhanced tissue repair, or increased energy levels do not align with the physiological effects of excessive radiation, which tends to disrupt normal biological processes rather than enhance them.
