Somatic radiation damage refers to effects on whom?

• A. Future offspring
• B. The irradiated individual
• C. Population genetics
• D. Environment

Answer: (B)

Somatic damage is about effects that occur in the body's own cells of the person who is irradiated. When radiation injures tissue, it can cause things like skin reactions, organ damage, or cancer in the exposed individual, and these changes happen to the person right here and now, not in their future offspring. The reason this isn’t passed to children is that somatic cells are not inherited; only damage to germ cells (sperm or eggs) could produce heritable changes in offspring. So the irradiated individual is the one who experiences somatic effects. The other options refer to outcomes that involve heredity, populations, or the environment, not the direct effects on the person exposed.
