Genetic effects are typically described as which of the following?

• A. Cancer and birth defects
• B. Only leukemia
• C. Skin burns
• D. No risk

Answer: (A)

Genetic effects from radiation refer to heritable changes that can be passed through germ cells to future offspring. The health outcomes commonly associated with these heritable changes are cancers and congenital anomalies, such as birth defects. So describing genetic effects as cancer and birth defects captures the idea that these are risks that may appear in subsequent generations due to mutations in reproductive cells. Leukemia is a specific type of cancer, not the only possible genetic outcome, and birth defects reflect inherited developmental issues rather than immediate tissue damage. Skin burns are acute somatic injuries from radiation to the exposed person, not inherited genetic changes. Saying there is no risk would be incorrect because genetic effects imply a real, though often small, risk of heritable conditions in offspring.
