What is the traditional unit used to denote operator dose?

• A. Gray
• B. Rad
• C. Sievert
• D. Rem

Answer: (D)

Operator dose is expressed as a dose equivalent to reflect the biological risk of different radiation types. The traditional unit for this is the rem, which stands for roentgen equivalent man. It combines the amount of energy deposited in tissue with a quality factor that accounts for how damaging different radiations are biologically. That makes rem a measure of potential harm to a person, not just energy absorbed. In modern practice, the SI unit for dose equivalent is the sievert, where 1 rem equals 0.01 sievert. The gray and rad are absorbed-dose units (energy per kilogram) and do not alone capture the varying biological effects of different radiations, which is why they aren’t used to denote operator dose. So rem is the traditional unit used to denote operator dose.
