Total equivalent dose for the embryo/fetus during gestation?

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

Answer: (C)

The fetal dose limit during gestation is the total allowable equivalent dose to the embryo/fetus over the entire pregnancy. The established limit is 0.5 rem (5 mSv, or 0.005 Sv). This value is set to protect the developing fetus while allowing necessary medical imaging for the mother. So 0.5 rem matches the recommended total gestational limit. The other options either represent monthly-like or much larger doses (0.05 rem is far below the total gestational limit, while 5 rem and 0.5 Sv are far above it).
