    I've crossposted this to because I know there are some knowledgeable
    people (radio) there.
    Britain's top health-protection watchdog wants the network, which emits
    radiation, to be full investigated because of the concern for students'

    Wi-Fi - described by the British Department of Education and Skills as
    a "magical" system that means computers do not have to be connected to
    telephone lines - is being taken up rapidly in schools there, with
    estimates that more than half of primary schools - and four-fifths of
    secondary schools - have installed it.

    But some scientists have expressed fears it could cause cancer and premature


    Kind of makes me wonder if I should go ahead with my planned wifi install at

    Its less RF power than cellphones or DECT or broadcast.
    Its a bit late to be worrying about radio frequency radiation.

    The less RF you are exposed to the better, it's probably no coincidence that
    left-handed cell phone users invariably end up with brain tumours on the
    left-hand sides of their brains! And yes, you guessed it, cell phone users
    who put their phones to their right ears, invariably get brain tumours on
    the right sides of their brains. Using the speaker phone on your cell phone
    and keeping the phone as far away from your ears as possible might just be a
    good idea.

    I've been using wifi for a couple of years, and I'm sure you won't want to
    end up like me!

    Social darwinism. Given that people overall are living longer and the
    population on the planet is exploding at an unsustainable rate, it
    stands to reason that a consequence of such expansion will also be an
    shorter lifespan for some.

  8. I think that should read "left-handed cell phone users _who get a brain
    tumour_ invariably end up with brain tumours on the left-hand sides of
    their brains". Which is still not true of course, but I do remember
    reading there may be a statistically significant difference for brain
    tumour side versus cell phone side. Of course since cell phone users
    don't seem to get brain tumours anymore often than non-cell phone users
    maybe it's merely the act of holding your arm up that causes brain

    Marconi sent and received his first radio signal in 1895 and since then
    man-made radiation has joined natural radiation around the earth. Since
    then life expectancy has greatly increased. If you are really concerned
    about a few microwatts from Wi_Fi when there are huge transmitters
    broadcasting kilowatts on the hill you should really get out more often.

    Do you really want everybody holding their cellphones at arm's length
    and SHOUTING at them? I don't think so!

    Don't computers themselves emit radiation anyway. They also offgas harmful
    chemicals. You do have to live your life, and not be too concerned,
    otherwise you would become a bubbleboy.

    "Invariably" is a bit strong. There is a correlation which can be dug out
    of the noise by using statistical methods on a huge sample is all. Modern
    cell phones are only operating at 100 milliwatts or so because of higher
    cell density and problems will be less than in the days when phones
    sometimes pumped out several watts to maintain a connection. Prudent
    behaviour is a good idea; use an external aerial in the car and in other
    difficult environments if you will be using the phone a lot there. Wi-fi
    is legally limited to 1 watt Equivalent Radiated Power and commercial
    units usually radiate 100mW or less. The inverse square law applies to a
    first approximation so this is much less of a concern than the cell phone
    held against the head. Wi-fi signals are almost at background levels and
    spread spectrum and frequency hopping techniques rather than raw power are
    used to achieve communication so I am not at all worried about wi-fi.

    definatly more then dect since that is so useless that it cant even
    cover a house and has a much lower datarate.

    Hell, I don't even use it and look at the state I'm in :)
    I'll be right tho if I switch to Linux LOL.

    Shit, I'm being silly tonite.

    The level next to your head is higher though.

    But the topic is wi-fi not cellphones.
    Which side of your head do you use for your laptop ?

    I think that people whose homes are very close to large power pylons have
    also been shown to be more at risk from radiation problems than people who
    live a long way from such pylons. People have often complained when powerful
    radio transmitters are built near to their homes or when cell phone base
    towers are built near schools etc. It is a bit foolish to dismiss the
    effects of RF on your health, particularly if you are a younger person whose
    brain is still growing and developing. Cancerous tumors can be caused by
    radiation, that's why they stopped x-raying peoples' feet when they were
    buying shoes. I agree with people who say that you shouldn't over emphasise
    the problem, but then, like anything, it pays to know that you may be taking
    risks with your health if you are continually exposed to high levels of
    radiation, such as living near a power pylon.

    And you might want to reconsider keeping your car keys with the alarm
    transmitter in your front pocket too. :)

    Sure. Make sure you also get rid of your mobile phone, cordless phone, and
    microwave too.
