Mylittleimps, you can't prove anything of any kind is safe. You can't prove any negative, that's Science 101.
Everything gives off microwaves. You are giving them off now.
Radiators in homes increase the amount of microwaves by at least a factor of 100.
Male teachers give off more microwaves than women, as do black people, and all of these people by coming near your child increase their exposure.
I can't prove this level is safe, actually it's basic undergraduate physics to show that a cup of tea will emit radiation of a kind that we know for a fact causes cancer.
I would ask you please to read my posts.
I'm not saying WIFI is safe, I've explicitly said that I don't know. However, I find it hard to see how it can be very dangerous.
What I am sad about is the arty hysteria over the whole thing, when there are vastly greater risks that are known, and ignored.
What I have railed against is the poor quality of debate by the anti-wireless groups and the BBC. Maybe there are risks, certainly we need research.
