Which statement best describes the occupational dose limit for minors relative to adult limits?

• A. 20% of Adult limits
• B. 10% of Adult limits
• C. 5% of Adult limits
• D. Equal to Adult limits

Answer: (B)

Minors have a smaller, safer exposure target because they’re more radiosensitive and have more years ahead for potential effects to show up. So occupational dose limits are set as a fraction of the adult limit. The standard fraction used is 1/10, meaning a minor’s allowed annual dose is ten percent of the adult limit. Since the adult occupational limit is 50 mSv per year (about 5 rem), the minor limit becomes 5 mSv per year (about 0.5 rem). In practice, this keeps exposure well below adult levels to protect developing tissues. If a workflow could push a minor’s exposure toward that 5 mSv/year cap, adjustments, shielding, or task changes would be needed.
