6. Gamma radiation can be stopped by:
- a cotton cloth soaked in ethanol
- a sheet of paper
- a lead block
- an aluminium sheet
7. What is the range in the air of beta- radiation?
- a few cm
- a few km
- a few m
- a few mm

9. Nuclear fusion is when 2 lighter nuclei fuse together to form what?
- A single heavier nucleus
- An electron
- Half an atom
- A proton
10. Why is nuclear fusion have to occur at high temperatures and pressures?
- To make an explosion, so a new element can be formed from the original particles.
- Because forces in the atmosphere are very high
- To provide energy needed to force the 2 positive nuclei together.
- To increase the rate of reaction.

- Vaporises, Ionises, Accelerates, Flight/ Drift Tube, Detector, Computer
- Vaporises, Accelerates, Flight/ Drift Tube, Ionises, Detector, Computer
