This sort of thing really annoys me. Sorry Pete, I know you put this up in good faith, I'm not bashing you.

So what is the prevention for cancer that is supposed to be caused by EMR? I can think of a few...
1 - Don't go near (or use) any high current appliances. Showers, electric cookers, kettles, toasters to name but a few.
2 - Don't use a mobile phone, Do not go near anyone with a mobile phone. They give out signals even when not in a call.
3 - Don't use wifi, or bluetooth.
4 - Don't use any computers, TV's, CD players or anything that resembles these items. They give off high frequency EMR.
5 - Avoid letting TV and radio transmissions from passing through you. These are after all forms of electromagnetic radiation too.
6 - Wear a full medieval armour plated suit. Or for the person on the move a foil wrapping should suffice. Try your nearest outdoors shop for some. Don't forget a metal hat too.
7 - Avoid light. This is also a form of electromagnetic radiation.

OK I admit I'm being ridiculous now! I'm just highlighting the fact that EMR is everywhere. Without it we would not be alive in the first place.

If you do not want to get cancer then my advice is don't smoke, drink in moderation, don't take medical drugs when it's not necessary (don't take a pill for your sniffles!), and eat well, not "chicken ding" crap (ready meal).

Will I take my own advice? Not fully, part of my enjoyment in live involves smoking something now and then, drinking a bit much when I shouldn't and taking some aspirin to cure the hangover. As for ready meals, I prefer my own food. The pyramid of food! :D
