What is the primary purpose of shielding in radiography?

• A. Improve image quality
• B. Protect staff only
• C. Minimize patient exposure and protect sensitive organs
• D. Cosmetic purposes

Answer: (C)

Shielding is used to lower the patient's radiation dose by protecting radiosensitive tissues from exposure during imaging. By placing protective barriers over areas like the thyroid, breasts, gonads, or eyes, we reduce both scatter and unnecessary primary exposure to these organs, helping to keep the dose as low as reasonably achievable while still obtaining the needed diagnostic image. While shielding can also reduce stray radiation to staff, the main goal is patient protection. It’s not about improving image quality and it certainly isn’t for cosmetic reasons.
