Exposure to 10 NCi for 10 Minutes Is More Hazardous

question 61

Multiple Choice

Exposure to 10 nCi for 10 minutes is more hazardous for a child than for an adult because

• A) the child's cells are dividing more rapidly than the adult's and are, therefore, more susceptible to the radiation.
• B) the child's smaller body size makes the effective dose larger for the child than for the adult.
• C) the child's immune system is not developed well enough to resist damage.
• D) the child's skin is not as thick as an adult's and cannot block as much radiation.
