Dose to that part of the body from the elbows to the fingertips and the knees to the toes is called what?

• A. Limb Dose
• B. Partial body dose
• C. Extremities Dose
• D. Local dose

Answer: (C)

Extremities dose refers to the radiation dose received by the limbs—the arms from the elbows to the fingertips and the legs from the knees to the toes. This region is treated as a separate category because the hands and feet can accumulate significant localized exposure, and monitoring is often handled differently from whole-body exposure. In practice, extremities dose is tracked with dedicated dosimeters on the hands or fingers, and regulatory limits for these parts of the body are set accordingly, typically allowing higher doses than whole-body limits due to the localized nature of the exposure. The other terms aren’t the standard way to describe this specific region: limb dose isn’t the formal regulatory term for the arms and legs; partial body dose is too general a descriptor for any non-whole-body exposure; local dose refers to a small, localized area and doesn’t specifically denote the entire limb.
