Equivalent dose is calculated by multiplying the absorbed dose by which factor?

• A. Effective dose
• B. Equivalent dose
• C. Absorbed dose
• D. Exposure

Answer: (B)

Biologically meaningful dose uses a multiplier that reflects how damaging the radiation type is. This multiplier is the radiation weighting factor, and when you apply it to the energy deposited in tissue (the absorbed dose), you get the equivalent dose. The equivalent dose accounts for differing biological effectiveness across radiation types and is measured in sieverts. For X-rays, gamma rays, and similar radiations, the weighting factor is 1, so the equivalent dose numerically matches the absorbed dose in grays, just expressed in sieverts. The choice you’re seeing corresponds to the quantity defined by that product—the equivalent dose.
