The cumulative occupational exposure for a 22-year-old radiographer is:

Explanation:
Cumulative occupational exposure is the total dose a radiographer has accumulated over their working life. In this exam’s approach, a simple way to estimate it is to multiply age in years by 10 mSv per year, reflecting the idea that exposure accumulates with time in the field. So at 22 years old, the estimate is 22 × 10 mSv = 220 mSv. That’s why 220 mSv is the best pick. The other values would come from using smaller yearly multipliers (for example, 1 mSv/year would give 22 mSv; 0.5 mSv/year would give 11 mSv; 5 mSv/year would give 110 mSv), which aren’t the convention used here. In real practice, the official annual limit is about 20 mSv, and lifetime limits are set by regulations, but the question uses this 10 mSv/year shorthand to illustrate cumulative exposure with age.
