What is the annual occupational effective dose limit for radiographers?

• A. 10 mSv
• B. 50 mSv
• C. 0.50 mSv
• D. 0.05 mSv

Answer: (B)

The main idea tested here is understanding the annual dose limit for workers exposed to ionizing radiation. For radiographers, the upper bound you should not exceed in a single year is fifty millisieverts. This cap helps keep cancer risk from radiation as low as reasonably achievable while allowing the practical exposure needed in clinical work. There’s also guidance that over five consecutive years the average should not exceed twenty millisieverts per year (about one hundred millisieverts in five years), but the question asks for the annual limit, which is fifty. The other numbers listed are not the standard annual occupational limit—they’re either far below or pertain to non-occupational (public) exposure levels.
