The Eye Dose Equivalent is the dose to the lens of the eye from external exposure. Which statement is correct?

• A. True
• B. False
• C. Not applicable
• D. Only for internal exposure

Answer: (A)

The Eye Dose Equivalent refers to the radiation dose that the lens of the eye would receive from external exposure, commonly expressed as Hp(3) for external radiation. It is defined specifically for external exposure, not for radiation inside the body. This makes the statement correct: the eye dose equivalent is the dose to the lens from external exposure. The lens is especially sensitive, so monitoring this quantity helps ensure workers stay within regulatory limits for eye protection. Internal exposure would involve dose from inside the body, which is not what Eye Dose Equivalent measures.
