Sample item

What material is commonly used for X-ray shielding?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Lead

Lead attenuates X-rays efficiently because of its high atomic number and density, so it is used in protective aprons and shielding where appropriate.

Option by option

  • A. Wood

    Wood provides poor X-ray shielding.

  • B. Cotton

    Cotton is not adequate radiation shielding.

  • C. Lead (correct)

    Correct: lead provides effective X-ray attenuation.

  • D. Glass

    Ordinary glass is not standard protective shielding.
