💡 Exam Tips for Background Radiation

🎯 Common Question Types:

Name two or three natural sources of background radiation [2-3 marks]
Calculate corrected count rate [2 marks]
Explain why background radiation varies with location [2 marks]
Explain the procedure for measuring background radiation correctly [3 marks]
State why background radiation readings vary from moment to moment [1 mark]

📝 Key Command Words:

Name/State — just give the source, no explanation needed
Explain — give the reason (e.g. why background must be subtracted)
Calculate — show the subtraction clearly with units
Describe — outline the method step by step
Suggest — reason from physics principles, may have multiple valid answers

⚠️ Common Mistakes to Avoid:

Forgetting to subtract background radiation from measured count rates in calculations
Saying nuclear power is a major source — it is less than 0.1%
Saying all background radiation is from artificial sources — 85% is natural
Forgetting that background radiation is random and varies — always average multiple readings
Confusing "dose" (sieverts) with "count rate" (counts per minute)
