What is the typical range for effective dose exposure to radiation?

• A. 0.01-0.05 mSv
• B. 1-5 µSV
• C. 0.1-0.5 rem
• D. 0.1-1 mSv

Answer: (B)

The effective dose exposure to radiation is typically measured in millisieverts (mSv), which is part of the International System of Units for measuring radiation dose. The range that is commonly referenced in various radiation exposure scenarios, including those related to medical imaging and other radiation sources, is between 0.1 to 1 mSv. This range takes into account various exposures that a person might encounter, such as from diagnostic imaging procedures or environmental sources of radiation. It reflects that, for standard procedures, the doses are designed to be within this level to minimize risks while still providing necessary diagnostic information. In contrast to other options, the value of 1-5 µSv, while it may represent very low exposures from certain sources, does not recognize common medical imaging exposures or cumulative annual radiation exposures. Additionally, the ranges expressed in rem (0.1-0.5 rem) convert to higher values in mSv (1 rem equals 10 mSv), making them not applicable to the typical effective dose exposure context meant by the question. The correct range of 0.1-1 mSv captures the majority of standard radiation exposure levels encountered in healthcare settings, where the emphasis is on keeping doses as low as reasonably achievable (ALARA principle)
