50 millisieverts is equal to how many rem?

• A. 0.5 rem
• B. 50 rem
• C. 5 rem
• D. 0.05 rem

Answer: (C)

Understanding dose units: rem and sievert are equal scales for assessing effective dose, with 1 sievert equaling 100 rem. To turn 50 millisieverts into rem, first convert to sieverts: 50 mSv = 0.050 Sv. Then convert to rem by multiplying by 100: 0.050 × 100 = 5 rem. So the correct value is 5 rem. (Other options would imply different conversions: e.g., 0.5 rem ≈ 0.005 Sv, 50 rem ≈ 0.5 Sv, 0.05 rem ≈ 0.0005 Sv.)
