Pediatric patients require special consideration and appropriate radiation protection procedures because they are more vulnerable to which?

• A. Only the genetic effects of radiation.
• B. Only the late somatic effects of radiation.
• C. Both the late somatic effects and genetic effects of radiation.
• D. Only the early somatic effects of radiation.

Answer: (C)

Children are more sensitive to radiation because their tissues are still developing and divide more rapidly, and they have many years ahead in which radiation-related effects can appear. This combination raises the risk of both late somatic effects (such as cancer that can develop years later) and genetic effects (heritable changes that could be passed to future offspring). At the doses used in pediatric imaging, early somatic effects are unlikely, so the greatest concerns are the long-term, later-appearing risks and potential hereditary effects. Therefore, protecting pediatric patients involves prioritizing the lowest reasonable dose and employing pediatric-specific dose optimization and shielding.
