Question

What provides protective shielding to both the imaging department and general public?

1) Lead aprons
2) Radiation badges
3) Lead-lined walls
4) Protective goggles

Answer 1

Lead-lined walls provide protective shielding to both the imaging department and general public.

Step-by-step explanation:

The correct answer is 3) Lead-lined walls.

Lead-lined walls provide protective shielding to both the imaging department and general public.

Lead is a dense material that can effectively absorb radiation, including X-rays and gamma rays. By lining the walls with lead, it prevents the radiation from spreading out and protects those outside the imaging department from unnecessary exposure.

For example, in dental imaging, a lead apron is placed over the patient, shielding surrounds the X-ray tube, and the technician stands behind a lead-lined door with a lead glass window. These additional measures further reduce the occupational and public exposure to radiation.
