What is the annual dose limit for occupationally exposed individuals 18 years of age and older?

• A. 100 mSv
• B. 65 mSv
• C. 50 mSv
• D. 55 mSv

Answer: (C)

The main idea is the annual limit on whole-body radiation for workers. For adults 18 and older who are occupationally exposed, the limit is 50 mSv per year (about 5 rem). This ceiling is set to keep the long-term cancer risk from radiation exposure low while still allowing workers to perform their duties. It refers to the effective dose to the whole body, not to a single tissue or organ. There are separate, smaller or different limits for specific parts of the body and for special situations (like pregnancy), but the standard annual occupational limit for adults is 50 mSv.
