What is the radiation exposure limit for individuals under 16?

• A. 1 mSv
• B. 10 mSv
• C. 3 mSv
• D. 0.1 mSv

Answer: (A)

The question is about the annual radiation dose limit for non-occupational exposure, including people under 16. The standard limit for the public is 1 mSv per year. This cap is set to protect individuals from the stochastic risks of ionizing radiation, especially in sensitive groups like children whose developing tissues can be more radiosensitive. The principle of keeping exposure as low as reasonably achievable (ALARA) guides these limits, balancing practical needs with health protection.

Options that propose higher numbers exceed the public limit, while a much lower figure would be unnecessarily restrictive for routine public exposure. So, 1 mSv per year is the amount designated to keep annual exposure within a safe, widely applicable bound for everyone, including minors.
