Across
- 3. The driving force that pushes electrons around a circuit .
- 5. This is used to measure the current through a component in a circuit.
- 10. Nuclear fusion involves joining 2 atomic nuclei to make a large nucleus.
- 13. Ionising living cells can damage them an cause this.
- 14. The flow of electrical charge/electrons around a circuit.
- 16. Anything in a circuit that slows down the flow of electrons.
- 17. The time taken for half the radioactive nuclei to decay.
- 19. In these types of waves, the vibrations are at 90 degrees to the direction of the wave.
- 21. This is used to measure the voltage across a component in a circuit.
- 23. The technique dating materials such as rocks or carbon by measuring the amount of radioactive isotope in the sample.

Down
- 1. Sound that has a higher frequency than humans can hear.
- 2. This type of resistor allows you to change the resistance.
- 4. The wire in a plug which is designed to prevent electric shocks and is coloured green/yellow.
- 6. Radiotherapy uses these types of rays to treat cancer.
- 7. In these types of waves, the vibrations are along the same direction as the wave is travelling.
- 8. These are used to detect leaks of radiation.
- 9. This is caused when two insulating materials are rubbed together, scraping electrons off one material and depositing them on the other.
- 11. The process of splitting atoms to release energy.
