What does mSv stand for?

• A. millirem
• B. millisieverts
• C. sieverts
• D. rem

Answer: (B)

mSv stands for millisieverts, the milli- prefix applied to sieverts in the SI system. The sievert is the unit used to express the biological effect of ionizing radiation, accounting for the amount of energy deposited and how different tissues respond to that energy. In diagnostic radiology, doses are typically small, so using millisieverts makes the numbers practical to read. For perspective, 1 sievert equals 100 rem, so 1 millisievert equals 0.001 sievert, or 0.1 rem. This convention lets us compare exposures across procedures and equipment. The other terms are older or different units (millirem and rem), but the standard SI unit here is millisieverts.
