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

Explanation:
The lens of the eye is particularly radiosensitive, so occupational limits were set to protect against radiation-induced cataracts. Historically, the annual limit for the lens has been 15 rem, which is 0.15 Sv or 150 mSv. This is why the correct choice matches that value. The other options don’t align with the long-standing lens limit (for example, 5 rem is far below the historical limit, while 50 rem and 100 rem are higher than what was historically permitted for the lens). Note that newer guidelines in some systems have moved toward lower lens limits, but this question reflects the traditional 15 rem per year standard.
