Question
- A. It can cause burns on the skin.
- B. It can lead to mutations and increase cancer risk.
- C. It can be easily removed from the body.
- D. It has no significant health effects.
Answer
The correct answer is B: It can lead to mutations and increase cancer risk..
Explanation
The correct answer is B: It can lead to mutations and increase cancer risk.. 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: It can cause burns on the skin.; It can be easily removed from the body.; It has no significant health effects..
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.
