Which statement about gonad shielding is true?

• A. It is always recommended for all radiographs
• B. It offers no dose reduction
• C. It reduces gonadal dose if placed properly and does not obscure diagnostic information
• D. It increases image noise

Answer: (C)

Gonad shielding lowers radiation exposure to the reproductive organs by absorbing some of the energy before it reaches them, but it only works well when the shield is placed correctly and does not cover any area that needs to be seen for the diagnosis. When a shield sits over the gonads and outside the area of interest, it reduces dose from scatter and some primary photons without obscuring important anatomy, so the image remains diagnostic. That’s why this statement is true.

If shielding blocks the region being imaged or is poorly aligned, it can obscure anatomy or degrade image quality, which is why you don’t shield for every radiograph and why shielding isn’t claimed to offer no dose reduction. Proper shielding also doesn’t inherently increase image noise when used correctly.
