What is the radiation exposure limit for individuals aged 16 to 18?

• A. 2 mSv
• B. 6 mSv
• C. 12 mSv
• D. 0.5 mSv

Answer: (B)

Young workers have lower radiation dose limits than adults to protect developing tissues and reduce lifetime risk. For individuals aged 16 to 18, the annual exposure limit is six millisieverts. This value is the maximum allowed dose in one year for an under-18 worker, and it sits between the much lower public exposure limit and the higher adult occupational limit (20 mSv per year, averaged over five years). In practice, dosimetry and safety measures aim to keep a young person’s yearly dose at or below this 6 mSv limit through shielding, distance, and minimizing time near sources. The other options do not fit because they are either well below this occupational limit or exceed it.
