no,
how much radiation do you get from a handheld vhf, 6 inches from your brain, or the ariel 2m behind you?

Or a 2kw RADAR 2 meters from your head

Hell, yes we should be worried. My Kids are growing up a world of Radiation, a little bit 24/7 over a long time....Got to do some damage!

This is where the inverse square law comes into play - basically any electromagnetic wave loses power a massive amount the further away it gets. So basically at 2x the distance the power is 1/4 the source and so on.

This racks up very rapidly so for example someone sleeping under an electric blanket gets more radiation than someone living directly beneath an electricity pylon.

Putting a mobile phone to your head is therefore worse than living by a mast even though the mast pumps out a few kilowatts as opposed to the phones milliwatts!!!

Having a laptop on your lap is worse than having the router a few feet from you etc.

Of course all this pales into insignificance compared to the crap the sun chucks at us every day - unless you live in Wales!!!

Background natural radiation can be much worse than the man made stuff!!!

As someone pointed out (on here I think) the ultimate health and safety sanction is to ban birth because it always leads to death.

There's no point worrying about it all - something will get you in the end!

Just concerns me that, in the absence of concrete evidence of adverse effects, wi-fi networks are being rolled out across the country. Lack of evidence of disease/biological effects does not mean wi-fi is safe - it just means that insufficient studies have been carried out.
Look at HRT - deemed "safe" (i.e. no evidence to the contrary) for ages and doled out left, right and centre - and now ....

Read my comments on the inverse square law - a few feet away from the source and the power levels are miniscule - much less than your mobile phone right by your head.

What about exposure over time? Could the effects of prolonged low level exposure be cumulative?
