CAIE IGCSE Physics 3.3.4 Harm from excessive EM radiation: (a)
Practise linking excessive electromagnetic radiation to risks and safety choices for microwaves, infrared, ultraviolet, X-rays and gamma rays.
How this is tested
- explain X-ray precautions using ionisation, cell damage, mutation or cancer risk
- link microwave-oven door design to preventing harmful microwave leakage
- choose shielding, distance or exposure time as a safety decision for X-rays
