Which protective measure must be used on children and potentially procreative patients when feasible, without compromising diagnostic information?

• A. Gonad shielding
• B. Grid
• C. Thermoluminescent dosimeter
• D. All of the above

Answer: (A)

Protecting reproductive organs from radiation is essential when imaging patients who are children or may conceive, and the protective measure that directly reduces exposure without sacrificing diagnostic information is gonad shielding. A properly placed shield over the pelvic area can significantly cut the dose to the gonads while still allowing the needed anatomy to be visualized, provided the shield does not obscure essential structures or interfere with the imaging technique. A grid, while useful for reducing scatter and improving image quality, is not a protective measure for the patient’s gonads and may even require higher exposure to achieve the same receptor exposure. A thermoluminescent dosimeter is a device used to measure dose, not a protective measure. Therefore, only gonad shielding fits the description of a protective measure used when feasible without compromising diagnostic information.
