Eye Dose Equivalent measures the dose to which tissue?

• A. The dose to the lens of the eye from external exposure.
• B. The dose to the skin from external exposure.
• C. The absorbed dose to the head.
• D. Internal dose to bone marrow.

Answer: (A)

Eye dose equivalent targets the amount of radiation energy that reaches the lens of the eye from external sources, reflecting the risk to the eye itself. The lens is particularly radiosensitive, so monitoring this specific dose helps protect vision and prevent cataracts. It’s different from skin dose (a shallow dose at the skin surface) and from internal dose to bone marrow (which involves radionuclides inside the body). It’s not the general absorbed dose to the head, but the lens-specific external exposure dose.
