Question

A. Alpha particles have high penetration power.
B. Alpha particles are strongly ionising and can cause significant damage to cells.
C. Alpha particles can be easily shielded by clothing.
D. Alpha particles do not affect living tissues.

Answer

The correct answer is B: Alpha particles are strongly ionising and can cause significant damage to cells..

Explanation

The correct answer is B: Alpha particles are strongly ionising and can cause significant damage to cells.. This supports the learning objective "Explain why alpha-emitting contamination inside the body is particularly dangerous." 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: Alpha particles have high penetration power.; Alpha particles can be easily shielded by clothing.; Alpha particles do not affect living tissues..

Common mistake

Alpha Radiation Danger

Students often think that alpha radiation is not harmful when inside the body because it cannot penetrate the skin.

Emphasize that alpha particles are highly ionising and can cause significant damage to internal tissues, making them particularly dangerous when ingested or inhaled.
