What is the annual occupational dose limit for the lens of the eye?

• A. 1.5 mSv
• B. 150 mSv
• C. 100 mSv
• D. 1.0 mSv

Answer: (B)

The lens of the eye is especially radiosensitive, so protecting it from occupational exposure is a priority to prevent cataracts. Historically, regulatory bodies set an annual limit for eye exposure at 150 mSv to keep the cumulative dose low enough to reduce this risk while allowing workers to perform necessary tasks. That’s why 150 mSv per year is the best match for the question. The other numbers either fall short of a protective limit or exceed what’s traditionally accepted for the lens in this context. (Note: some newer guidelines have proposed lower limits, but this question aligns with the older standard.)
