What is the protective purpose of a lead apron and thyroid collar during radiography?

• A. To protect the operator from radiation.
• B. To reduce scatter radiation exposure to the patient.
• C. To prevent reflections.
• D. To improve image sharpness.

Answer: (B)

The main idea is protecting the patient from scatter radiation. When an X-ray beam passes through the body, some photons scatter in different directions. That scattered radiation can reach and dose tissues outside the primary beam, including the thyroid and reproductive organs. A lead apron and thyroid collar absorb much of this scattered radiation, reducing the dose to those protected areas. They don’t change the image quality or sharpness, and they don’t serve to shield the operator—that indirect protection comes from other shielding practices.
