hard · MCQ · Q-08D56D
According to current International Commission on Radiological Protection (ICRP) recommendations, what is the occupational dose limit for the lens of the eye, averaged over 5 consecutive years with no single year exceeding a specific limit?
- A.20 mSv per yearCorrect answer
- B.50 mSv per year
- C.150 mSv per year
- D.500 mSv per year
Solution
The ICRP revised the occupational dose limit for the lens of the eye downward to 20 mSv per year, averaged over defined periods of 5 years (100 mSv in any single year), following evidence regarding radiation-induced cataracts at lower thresholds.
