5 rem is equivalent to how many millisieverts?

• A. 50 mSv
• B. 5 mSv
• C. 0.5 mSv
• D. 500 mSv

Answer: (A)

Understanding dose units: the rem and the millisievert are both used to express dose equivalents. The key conversion is 1 rem = 0.01 Sv = 10 mSv. Therefore, 5 rem equals 5 × 10 mSv = 50 mSv. A quick cross-check: 1 Sv equals 100 rem, which also confirms that 5 rem is 0.05 Sv, or 50 mSv.
