Question
- A. Only gamma radiation
- B. Only beta radiation
- C. Only alpha radiation
- D. Alpha, beta, and gamma radiation
Answer
The correct answer is D: Alpha, beta, and gamma radiation.
Explanation
The correct answer is D: Alpha, beta, and gamma radiation. This supports the learning objective "Explain how a Geiger-Muller tube can be used to detect nuclear radiation." in Radioactive decay and nuclear radiation 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 decay and nuclear radiation idea: Only gamma radiation; Only beta radiation; Only alpha radiation.
Common mistake
Misunderstanding Geiger-Muller Tube Function
Students often think that a Geiger-Muller tube measures the amount of radiation rather than detecting the presence of radiation.
Clarify that the Geiger-Muller tube detects radiation by counting the number of ionising events, indicating the presence of nuclear radiation.
