Basically you need to write about the dangers of x-rays and infra red…
- X-rays are higher frequency, ionising, can cause damage to cells/mutations/cancer etc. They are more dangerous than IR
- Infra-red is lower frequency, non-ionising, less dangerous but can cause overheating and burns
- But then need to draw a conclusion… is the IR device too risky full stop? Or is it safe for the specialist and maybe not the public? Training, regulation, safety?
- That last bit will get you the full marks!
This one could come up again, have a go, write yourself a model 6 mark answer…
