How Bad Can Wi-fi Be?
An anonymous reader writes "Sunday night in the UK, the BBC broadcast an alarmist Panorama news programme that suggested wireless networking might be damaging our health. Their evidence? Well, they admitted there wasn't any, but they made liberal use of the word 'radiation', along with scary graphics of pulsating wifi base stations. They rounded-up a handful of worried scientists, but ignored the majority of those who believe wifi is perfectly harmless. Some quotes from the BBC News website companion piece: 'The radiation Wi-Fi emits is similar to that from mobile phone masts ... children's skulls are thinner and still forming and tests have shown they absorb more radiation than adults'. What's the science here? Can skulls really 'absorb' EM radiation? The wifi signal is in the same part of the EM spectrum as cellphones but it's not 'similar' to mobile phone masts, is it? Isn't a phone mast several hundred/thousand times stronger? Wasn't safety considered when they drew up the 802.11 specs?"
Think of the children!!!
Seriously, it's sad that supposed "news" programs air things like this just to get ratings. What's even sadder is that lots of people believe them, so tech-savvy people like us now have to spend time explaining to Aunt Jane that the big evil wifi will not give her cat cancer.
All day we're around Microwaves, XRays, High voltage lines, lights, televisions and Radio signals. There are TONS, of course... but how much more is actually from outside the atmosphere?
The only thing that's frying our kid's brains are their ideas. I'm not overlooking child safety, but there are WAY more harmful waves out there than WiFi.
In the meantime, their children are outside getting burnt without sunscreen.

admitting in the brief write-up that there isn't any science behind this?
/. against ANY suggestion that wifi or cell phone signals MAY cause some adverse health effects is sloppy, anti-science thinking.
/. != FUD.
/. is FUD. /. is only anti-FUD in regards to its pet causes.
Maybe they read the article, which points out various scientists who argue that there IS evidence about it.
I've got to say, the ridiculously emotional backlash I see on
I personally don't believe cell phone signals or wifi signals are strong enough to cause health problems. But I'm certainly not going to be arrogant enough to proclaim that there absolutely are no health problems and we shouldn't even look at the problem.
I thought
Please, half of
he scientific method is:
1. Observe.
2. Hypothesise.
3. Test.
4. Repeat.
Presumably this scientist was on phase 3; attempting to test his hypothesis. When they testing indicated that the hypothesis was false, he altered it to conform to the newer observations.
Unfortunately life is not Star Trek. The pragmatic method is:
1. Hypothesise.
2. Beg.
3. "Prove".
4. Publish.
Science costs money. Money comes from benefactors. Benefactors don't like surprises. You publish the results you were paid to discover, or you don't get more money. Welcome to the real world. Wear a helmet.
