Question
- A. Higher than alpha radiation
- B. Lower than alpha radiation
- C. Equal to alpha radiation
- D. Non-existent
Answer
The correct answer is B: Lower than alpha radiation.
Explanation
The correct answer is B: Lower than alpha radiation. This supports the learning objective "Compare alpha, beta and gamma radiation in terms of ionising power." 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: Higher than alpha radiation; Equal to alpha radiation; Non-existent.
Common mistake
Ionising Power Confusion
Students often confuse the ionising power of alpha, beta, and gamma radiation, thinking they are similar.
Remember that alpha radiation is strongly ionising, beta radiation is moderately ionising, and gamma radiation is weakly ionising. Use a table to compare their properties.
