In medical imaging departments, radiography staff often wear protective aprons containing lead. Why is lead used in these aprons?
Lead reflects X-rays away from the body.
Lead absorbs X-rays, preventing them from passing through.
Lead neutralises the charge of the incoming radiation.
Lead accelerates the decay of the X-rays.
