For 10 minutes, an individual received 120 mrad per hour dose rate. How much exposure did the person receive?

Explanation:
Dose accumulates with time at a constant rate, so total exposure equals dose rate times how long the exposure lasts. Convert 10 minutes to hours: 10/60 = 1/6 hour. Multiply: 120 mrad/hour × 1/6 hour = 20 mrad. So the person received 20 mrad of exposure. (Another quick check: 120 mrad per hour is 2 mrad per minute; over 10 minutes that also gives 20 mrad.)
