Question: 1 / 400

What substance is used to prevent x-ray exposure?

Plastic

Lead

Lead is used as a protective barrier against x-ray exposure due to its high density and ability to absorb x-rays.

Plastic, rubber, and copper are not as effective as lead in preventing x-ray exposure. Plastic and rubber are not dense enough to absorb x-rays, and copper does not have as high of a density as lead. Additionally, plastic and rubber may even increase the amount of exposure by allowing scattering of x-rays, and copper is more commonly used in electrical wiring rather than as a shielding material in x-rays.
