What is one effect of nuclear radiation on living organisms?

Nuclear radiation has a significant impact on living organisms primarily through its ability to penetrate biological tissues and ionize atoms, which can cause damage to the cellular structure and DNA. When radiation interacts with cells, it can lead to potential harm or mutation in the cell’s DNA, resulting in various consequences. These mutations can disrupt normal cellular functions, potentially leading to cancer or other health complications. This harmful effect is a well-documented consequence of exposure to ionizing radiation, highlighting the risks associated with nuclear materials and radiation sources.

The other options suggest positive outcomes of radiation, such as increased growth rates, healthy cell division, or enhanced immune responses, which do not align with the established scientific understanding of the detrimental effects of nuclear radiation on living cells.
