💡 Exam Tips for Radiation Detection
🎯 Common Question Types:
- Explain how a GM tube detects radiation [3-4 marks]
- Describe cloud chamber tracks for alpha and beta particles [3 marks]
- State why workers wear film badges [2 marks]
- Calculate corrected count rate after subtracting background [2 marks]
- Compare detectors for a given application [3 marks]
📝 Key Command Words:
- Explain how — give the mechanism, step by step
- Describe — say what it looks like or what happens
- Compare — give similarities and differences with context
- State — brief answer, no explanation needed
- Calculate — show working with units in answer
⚠️ Common Mistakes to Avoid:
- Saying GM tube "absorbs" radiation — it ionises gas, not absorbs
- Confusing count rate with activity — they are related but not identical
- Saying film badges protect workers — they monitor dose, not shield
- Saying gamma leaves tracks in a cloud chamber — it does not (no charge)
- Forgetting to subtract background when calculating corrected count rate
