Question

A. Increase time spent near the source
B. Use shielding materials
C. Decrease distance from the source
D. Wear no protective equipment

Answer

The correct answer is B: Use shielding materials.

Explanation

The correct answer is B: Use shielding materials. This supports the learning objective "Explain why a contaminated object can continue to emit radiation." in Radioactive contamination because it uses the correct atomic and nuclear radiation relationship for Atoms and nuclear radiation. The other options are less suitable because they do not match the required Radioactive contamination idea: Increase time spent near the source; Decrease distance from the source; Wear no protective equipment.

Common mistake

Contaminated Object Emission

Students often think that a contaminated object stops emitting radiation once it is removed from the radioactive source.

Emphasize that a contaminated object continues to emit radiation because it contains radioactive atoms, regardless of its location.
