Question

Which metal aprons are worn by a radiographer to protect him from radiation?

• A. Mercury coated apron
• B. Lead apron
• C. Copper apron
• D. Aluminiumised apron

Hint:

High density, high atomic number materials like lead are best radiation shields, especially for X-rays and gamma rays.

Answer 1

The Correct Option is B

Step 1: Type of radiation in radiography.
Radiographers are exposed mainly to X-rays and gamma rays.
Step 2: Best shielding material.
Lead has high atomic number and high density.
Hence it absorbs X-rays effectively due to photoelectric effect.
Step 3: Therefore protection used.
Radiographers wear lead aprons.
Final Answer: \[ \boxed{\text{Lead apron}} \]
