Which of the following is NOT a listed long-term effect of chronic radiation exposure?

• A. Cancer
• B. Genetic effects
• C. In-utero effects
• D. Skin aging

Answer: (D)

Chronic exposure to ionizing radiation carries long-term risks that show up years later and after many exposures. The main concerns are an increased lifetime risk of cancer, potential genetic (heritable) effects, and effects on a developing fetus if exposure occurs during pregnancy. These outcomes arise from radiation’s ability to damage DNA, and such damage can influence health long after the exposure event.

Skin aging is not listed as a standard long-term effect of chronic radiation exposure in safety guidance. While radiation can cause localized skin damage or look like aging at the exposed site, the broad, systemic idea of “skin aging” isn’t treated as a primary long-term risk in the same way as cancer, genetic changes, or fetal development impacts.
