Biological effects refer to the effects of radiation on cells including no damage, damage and repair, cell death, mutation and survival. Which option correctly identifies this concept?

• A. Somatic effects
• B. Biological effects
• C. Genetic radiation
• D. Chronic radiation exposure

Answer: (B)

Biological effects describe the full range of how radiation impacts cells, from no change at all to damage that is repaired, to cell death or mutations, with the cell and organism possibly surviving. This term captures both the immediate cellular responses and the long-term outcomes that can result from exposure, including repair processes and genetic changes. The other terms refer to narrower ideas: somatic effects concern effects on the body’s tissues and organs in the exposed individual; genetic radiation refers specifically to heritable changes passed to offspring; chronic radiation exposure describes a pattern or duration of exposure rather than the cellular outcomes. So the statement aligns with the broad concept of biological effects on cells.
