Parents' Campaign Leads To Wi-Fi Ban In New Zealand School

drmofe writes "Two parents in New Zealand have orchestrated the removal of a school's Wi-Fi system. They have expressed the concerns that Wi-Fi causes cancer and other health issues. The child of one of these parents died recently from brain cancer. This appears to be an emotional area and one where decisions appear to be being made without evidence. The NZ Ministry of Education provides guidelines for the safe use of Wi-Fi in schools and the school itself was operating within those guidelines."

There's a question about that at Skeptics

[satuon]

There's a question about that are Skeptics stack exchange - http://skeptics.stackexchange.com/questions/1178/are-wifi-waves-harmful

This is the answer:

===============

WIFi is non-ionising radiation and so has similar issues to other radiation using similar frequencies such as mobile telephones and microwave ovens. These produce heating effects. WiFi is not focused, so any impact should be very small and perhaps not measurable.

I am not aware of any health studies specifically on WiFi. There have been studies on mobile phones which has shown that while the phone is in use and held next to the head, there is small but measurable heating effect on human tissue. My guess is that it has less impact than standing at right angles to the Sun so one side of the head gets warmer faster than the other. Even then, these studies have produced no evidence that this has any health impact, positive or negative:

A large body of research exists, both epidemiological and experimental, in non-human animals and in humans, of which the majority shows no definite causative relationship between exposure to mobile phones and harmful biological effects in humans.
And per Dr. Michael Clark of the HPA, WiFi is a fraction of the energy of a cell phone:

“When we have conducted measurements in schools, typical exposures from wi-fi are around 20 millionths of the international guideline levels of exposure to radiation. As a comparison, a child on a mobile phone receives up to 50 per cent of guideline levels. So a year sitting in a classroom near a wireless network is roughly equivalent to 20 minutes on a mobile. If wi-fi should be taken out of schools, then the mobile phone network should be shut down, too — and FM radio and TV, as the strength of their signals is similar to that from wi-fi in classrooms.”
The Sun does emit ionising radiation (ultra violet) and that has significant health effects such as sunburn, pigmentation changes and Vitamin D production. WiFi's impact, if anything, is nothing like this.

For the record, the sun's heating and radio wave heating would work differently. The sun heats the surface. The sun wouldn't do a particularly good job of heating the brain. The scalp would heat up, but then blood does a pretty good job of distributing that heat around, and the skull would be a decent insulator. Radio waves would penetrate into the brain and heat it directly.

Furthermore, there is at least one study showing that glucose metabolism in the brain increases in the presence of cell phone radiation.

Having said all of that, there's pretty much no way that either cell phones or WiFi are causing brain cancer. We've been engaged in a natural experiment of the effect of these forms of radiation. Both WiFi and cell phone usage have gone from "doesn't exist" to "ubiquitous" in the course of the last couple decades. We're not seeing an increase in any cancer rate that would show a correlation (let alone causation) with the rather dramatic increase in exposure to such radiation.

These parents want someone/something to blame for their child's death. It's very much that simple.

Blaming wifi or cell phones is easy. Actually digging around and finding the true cause of the cancer is hard.

It would be finding the cause of a specific cancer. Since that would be a combination of both how a cell malfunction and how it got missed by the immune system.

Besides, you might discover the cause was environmental, say, the coating on some cookware, or contaminants in food, drink, laundry detergent, whatever. And discovering a household product triggered a cancer is actionable.

Like many other things cancer is probably G by E. Involving the interaction of both genetic and environmental factors. So there is no single "cause" in the first place.
That's before even considering that some of the potential environmental factors might actually be common or even considered "healthy".

And sometimes it'll just be a chance mutation in a single cell division with absolutely no external contributing factor at all.

There are a million and one causes of cancer. You're exposed to many (toothpaste can cause cancer, eating fruit can cause cancer). You can't determine which of them was the cause.

But everyone needs something they can blame, since doing otherwise leaves them feeling powerless. It's a coping mechanism.

Re:There's a question about that at Skeptics

[Vitriol Angst]

I'd say that I somewhat agree with the "has no effect" position, but only because of dumb luck. Between WiFi and Cell Phones -- the cell phone will have 1000x more chance of being a problem because you hold it right to your face. So just based on the "square of the distance" law with signal strength alone, it's going to be too low.

However, I do believe that EM fields are going to have an effect -- it's just that it's likely based on a specific frequency and it would "interrupt" the absorption of certain nutrients -- so the effect isn't direct but would cause symptoms and those symptoms would also be impacted by someone's lifestyle and metabolism. Cells have what is called a "Calcium gate" and that resonates depending on what signals it gets from the cell nucleus and this impacts what types of ionized molecules are let through -- attracted to the net positive potassium charge inside the cell. I'm not sure if this is part of the textbooks or not, but it will be I'm fairly sure. This resonance should be influenced based on what ions it's trying to attract and an EM field frequency -- but only a very specific one. And I'm not sure even if that's going to be in mHZ or kHZ -- I've not seen research on it yet.

We are just getting into the age where we have to figure out how complex systems are impacted. Currently, one drug and one pesticide can get approval when tested as one drug and one pesticide, and the same for EM fields. We don't know how to test for thousands of interactions. So the "cause = effect" scenario where there is positive proof is hard to find -- but it should be there in the real world. We just have a larger petri dish to contend with these days.

The growing angst of primitive fear I understand -- it's not just that things are too complex and people are Luddites, I think it's proper to question when things cannot be proven safe. There are too many who are ready to gloss over issues of immunization, EM effects and GM foods because there is no 1-to-1 case study showing "add X and get Y result." Toss in every letter of the alphabet and people just start getting sick in random ways. And human reason and emotion just lends itself to a vague sense of unease which results in irrational responses.

I only see these kinds of debates heating up because it's really hard to prove something definitive if we don't have an explanation of why more people are getting certain maladies.

Currently, one drug and one pesticide can get approval when tested as one drug and one pesticide, and the same for EM fields.

It doesn't help that the FDA in the US is now so heavily compromised. Much of their funding comes directly from the companies asking for approval of their products, which means that the FDA is now working directly for the manufacturers (they are signing the checks). This puts it in a similar situation to the big 3 "approved" rating agencies and their role in the US mortgage banking crisis. They were providing AAA ratings to bundles of mortgages loaded with sub-prime loans. It brought the entire banking system to crisis.

So what happens when the FDA is being paid by producers? We've already seen many drugs get approval, then pulled months or years later when it's discovered they are killing people. The FDA is now funding swat raids on farms selling raw milk while putting bans on cheap commodities like red yeast rice so pharmaceutical companies can make big money on patents for the same ingredients (lipitor, for one). It's much worse than just not knowing how to do the research, it's that there is no one willing to even try, since all the money for it is coming from the ones producing the products.

For all your whining about how the government can't do anything right, you little twits haven't grown up on top of a waste chemical disposal trench. Our tax dollars made sure of that.

Therefore stealing resources from the productive elites for the sake of protecting the looters, the latter which is a bad thing in itself. After all, those destined for greatness will become rich enough to move elsewhere, and those who can't afford to should just die already. Nothing matters except the ego of the supermen.

You really don't get how these people think, do you? For all its anti-government creed, Objectivism is simply another totalitarian philosophy about reorganizing society based on some lunatic's idea of how everything should work to reach some utopian state of eternal bliss. And like its contemporaries fascism and communism, it too is not shy about breaking eggs to make an omelette. So telling a Randroid your tax dollars helped close an open chemical sewer is about the same as telling a neo-Nazi your tax dollars helped bring down the Third Reich.

â EMR accelerates the reaction rate, i.e., electron transfer rate
â EMR competes with the chemical force driving the reaction, so the effect of EMR varies inversely with the reaction rate

â Effects vary with frequency, and there appear to be different optima for the reactions studied: ATPase (60Hz), cytochrome oxidase (800Hz), BZ (250Hz)

These properties, in addition to stimulation of DNA in the cellular stress response, are consistent with EMR effects on many biological systems through interaction with electrons moving during redox reactions and also within DNA"

And discovering a household product triggered a cancer is actionable. Best blame it on the wifi and shift the attention of the pitchforks and torches brigade.

The IEEE Spectrum once had a big news story looking at the scientific evidence on the health effects of electromagnetic fields from power lines.

First question: How much EMF is there in the environment, and where is it coming from? There were studies that measured the EMF in households near power lines and away from power lines.

The strongest sources of EMF were food blenders, electric razors, and hair dryers. They were much stronger than power lines. And the ordinary 120v ac circuits in households were stronger sources than power lines in the back yard.

(Yes, they were intermittent sources, but the (weak) evidence of hypothetical damage (or at least biological effects) showed that intermittent sources had more of an effect (in tissue culture, among others) than constant sources.)

So I used to tell people, "If you're worried about power lines, why aren't you worried about the power lines in your baseboards?"

I did a bit of research into Love Canal at that time. (For the record, the best summary I read was an article in C&EN.)

The birth defects were the big problem, and I tried to find the studies. They weren't published, and the EPA told me they contained confidential medical information.

I later figured out the significance of that.

One of the major causes of birth defects is a sexually transmitted virus, and if you were trying to explain a cluster of birth defects, that would be one of the first things an epidemiologist would look for.

Another cause of birth defects is genetic damage. You could have clusters, as a result of a family with one mutation, like the Amish.

That's interesting and may well be true, however can we please step back from the copse of trees to see the whole forest? That DNA is a fractal antenna is an interesting bit of trivia, but requires context for proper interpretation of what that means when applied to the scope of our everyday lives. Electromagnetic radiation is not a human invention, it has always existed, both in ionizing as well as non-ionizing wavelengths. For the average person, even in our electronic age, natural sources account for the greater portion of our day-to-day electromagnetic radiation exposure.

While it only deals with ionizing wavelengths I still want to call upon XKCD's radiation dose chart because it provides some much needed perspective. I would further like to include a nice little tutorial on EM. Before we even begin to pick on WiFi, there are plenty of other things in modern society we should ban first including, the Sun, cordless phones, cell phones, TVs, microwave ovens, electric space heaters, electric motors, baby monitors, analog radio stations, high-voltage power lines, etc.. I find it simply amazing how the same people whom are so concerned about radiation from cell phones, will think nothing of placing a baby monitor right next to their child's crib.

Right. I took a course like that too.

One of the high points of my physics student days was figuring out the equation for the interference pattern of monochromatic light coming through a narrow slit. It was amazing. You integrated from one edge of the slit to the other, and got a big peak. Then you multiplied that by a sine function and got the interference patterns.

Re:There's a question about that at Skeptics

Well, our body is well evolved to handle natural sources of radiation which, nonetheless, can absolutely harm us.
We can handle a surprising amout of damage from UV, which luckily does not penetrate our entire body. And we've evolved to handle certain other kinds of radiation damage, heck, there's that evidence of hormesis. I don't know how that applies across the wholebody, nor how persistently high levels over a lifetime might cause an issue.

I also don't know how to address all the sources you listed because, well, I don't know much about this, that's why I was asking here. I did look for solar flux at radio frequencies here: http://www.astro.ethz.ch/people/pdf_files/benz/LBReview_thermal.pdf and if I'm reading the units right, it is not even close to being on the same scale, but... not sure really.
And I certainly don't know the power of all those other various sources.

But, this was interesting.
https://en.wikipedia.org/wiki/DBm

So, seems to me from that chart and inverse square estimate, that a cellphone up close against you would have 500x the wattage of an FM radio station 10km away. Not that that dude's research was necessarily exculpating FM radio stations.

Glancing at the technical data here...
http://www.bag.admin.ch/themen/strahlung/00053/00673/03012/index.html

Seems like a baby monitor transmits about 100mW which is about 1/5th the power of the phone and of course not pressed against the flesh. Sooo.... if the cellphone is cranking out 500mW at say 1cm from some part of the body you might be concerned about, and the baby monitor is cranking out 100mW but 100cm away, then presumably the baby monitor is 1/50,000th the concern of the cell phone, right?

From the article, and poorly formatted in this comment box:

At the time of the dump's closure, Niagara Falls was entering an economic boom and the population began expanding drastically, surpassing 85,000. The Niagara Falls City School District needed land to build new schools, and attempted to purchase the property from Hooker Chemical that had been used to bury toxic waste. The corporation initially refused to sell citing safety concerns, however, the board refused to capitulate.[1] Eventually faced with parts of the property being condemned and/or expropriated, Hooker Chemical agreed to sell on the condition that the board buy the entire property for one dollar. In the agreement signed on April 28, 1953, Hooker included a seventeen-line caveat that explained the dangers of building on the site. Hooker believed it was thus released from all legal obligations should lawsuits arise in the future.[9]

"Prior to the delivery of this instrument of conveyance, the grantee herein has been advised by the grantor that the premises above described have been filled, in whole or in part, to the present grade level thereof with waste products resulting from the manufacturing of chemicals by the grantor at its plant in the City of Niagara Falls, New York, and the grantee assumes all risk and liability incident to the use thereof. It is therefore understood and agreed that, as a part of the consideration for this conveyance and as a condition thereof, no claim, suit, action or demand of any nature whatsoever shall ever be made by the grantee, its successors or assigns, against the grantor, its successors or assigns, for injury to a person or persons, including death resulting therefrom, or loss of or damage to property caused by, in connection with or by reason of the presence of said industrial wastes. It is further agreed as a condition hereof that each subsequent conveyance of the aforesaid lands shall be made subject to the foregoing provisions and conditions.[1] ”

Roman_mir tried to convince me that the reason the Cuyahoga River burned was because it didn't have an owner. Everything in RonPaulLand apparently should have an owner, there are no Commons. The owner of the Cuyahoga River would have sued the companies dumping into it, they would have stopped, and everything would have been wonderful. When asked about why the owner wouldn't have just licensed them to pollute it as much as they wanted, or just sold it to the chemical and paint companies, the reply was that the owner of the next waterway downriver would have sued. Apparently Lake Erie needs an owner as well.

Not sure why every Libertardian solution that touches on the Commons needs thundering herds of lawyers, but apparently in RonPaulLand judges and juries are always competent and uncorruptable.

The point is that more people aren't getting these maladies. At least not in any way that would correlate with the dramatic increase in exposure to cell phone and WiFi signals.

But I do agree that we can almost certainly show that signals of these types do show up as at least minor changes in cell activity. But is that leading to brain cancer? If it is, then where's the brain cancer spike we should see related to the spike in exposure to these signals?

From TFA:

Science Media Centre manager Peter Griffin says the death of Te Horo pupil Ethan Wyman from a brain tumour was a tragedy for his family, friends and school mates, but that to blame it on wi-fi is wrong.

Mr Griffin notes there is no evidence anywhere in peer-reviewed literature to suggest wi-fi signals pose an elevated risk of developing brain cancers.

And also:

In a statement, the Te Horo School board said it would take wi-fi out of junior classes and replace it with ethernet cable. However, wi-fi will not be removed from the senior school due to the wishes of parents who were surveyed on the issue.

The board says it shares the government's view that wi-fi is safe.

"We have sourced information from the Ministry of Education, the Ministry of Health and other submissions," the board's statement says.

"Based on this information the board believes that Wi-Fi does not pose a health risk to staff or students."

So it really is just a couple of dumb people putting pressure on the school and not indicative of the school's or Ministry of Education's thoughts at all.

As much as I think that these Kiwis are being a bit cracked (though, by the standards of grieving processes for dead children, I've certainly heard stupider strategies...), those are terrible 'educational' points.

They fall in the horrible zone of being nonfalse; while also eliding virtually all the important distinctions, and providing the poor sucker handed them basically no useful information on which to found decisions.

Is RF in the 2.4 and/or 5GHz band electromagnetic radiation, and thus in the same broad category as (much) of what the Sun emits? Sure. Is that largely meaningless when the flavors of electromagnetic radiation run from extremely longwave RF whose interactions with matter are barely discernable without specialized antennas, all the way to very high energy gamma radiation, with a lot of variety in between, and numerous different uses and effects for various bands? Unfortunately so.

Do we all emit radiation? Sure, in modest quantities. Does that tell us anything useful about radiation safety? Only that the default dose is higher than zero, and that apparently doesn't kill you horribly most of the time. Nothing else.

If you want to talk about safety, arguments from broad classes of things that have some nominal commonality are painfully useless. If you aren't at least introducing concepts related to dosage, population level statistical study, various epidemiological techniques, you are basically just waving your hands from first principles.

Re:Wouldn't someone think of the children?

Those parents who have lost a child must be heartbroken and grasping at anything to give some sort of meaning to their son's death. Removing WiFi from junior classes may be senseless, but it gives these parents some sort of resolution and justification for what happened. Just let them have this one; WiFi access isn't really necessary in junior classes anyway and they can switch it back on in a few years if needed.

I agree. I didn't mean to say the school was doing something 'bad' by taking away the WiFi. The parents are wrong, but they're also heartbroken and it's probably not going to cause any harm to remove the WiFi from these junior classes. I think the school did exactly the right thing - deny that WiFi is harmful (the truth), but take it away anyway in order to appease these people.

Re:Wouldn't someone think of the children?

Re:Wouldn't someone think of the children?

I think the school did exactly the right thing - deny that WiFi is harmful (the truth), but take it away anyway in order to appease these people.

Unless there were expensive consequences to leaving the WIFI there, for example a very expensive lawsuit, then no I don't think they did the right thing. Removing the WIFI is a tacit admission that concerns about WIFI are valid. All the parents, friends of parents, children etc all know that a school took WIFI out of classrooms because of concerns about cancer. I agree that sometimes very minor (pointless) concessions can be justified on compassionate grounds, however I think this kind of concession isn't as minor as you do.

Re:Wouldn't someone think of the children?

[YttriumOxide]

What's sad is the people who occasionally have something worth sharing but are so completely unable to understand the need to be polite that they can't share it effectively.

This, I agree with. But only because of the limitations and requirements of the society we're in. I think it's sad that people are unable to effectively get their point across because it means that a potential for sharing information (and therefore increasing overall human knowledge) is lost.

The fact that it benefits an argument for it to be delivered clearly and politely isn't a bad thing unless you think a society in which such things are valued at all is a desirable outcome.

I'm taking a more abstract view here and imagining a world that we don't have. If no-one took offence at the style of how something is said and instead concentrated only on what was said, I believe that it would be a better world than the one we do have. More information would be shared, people would be happier, and misunderstandings would be fewer.

I fully agree though that we don't live in such a world, and therefore politeness is definitely important.

Re:Wouldn't someone think of the children?

[YttriumOxide]

I think it's a matter of weighing the statement they made vs the action they took. Perhaps it's a cultural difference between us, but as a New Zealander myself, I believe that most other New Zealanders would pay more attention to the fact that they said, "we don't think it's harmful" than the fact that they removed it.

It is fairly clear that they removed it in order to appease the complainers and not out of any perceived harm.

If I thought the risk of false belief was higher (i.e. people paying more attention to the action than the words) then I'd complete agree with you that the action would be too much as it would spread the false belief further, causing additional problems in the future.

Re:Wouldn't someone think of the children?

WiFi in the 2.4GHz band is very close to the frequencies used in microwave ovens to cook food. Water molecules are "tuned" to that frequency and will absorb that energy most efficiently. It's part of the reason Wifi has that less-regulated spectrum assigned to it as it doesn't propagate over long distances very well especially if the air is damp or humid.

At the signal levels used in a classroom it's very unlikely to impossible a Wifi system will cause any kind of noticeable heating effect in body tissues. Having a couple of hundred watts of 2.4GHz RF bouncing around inside a commercial aircraft fuselage is starting to get into microwave oven territory though...

The R&D site has a massive base-station so that the phones would lower their transmission levels, thereby preventing the cancer of course.

Similarly, us in the telecoms industry have a conspiracy where we convince school boards that radiation is dangerous and get all wifi removed plus base stations placed far away. This ensures that the phones emit the high levels of cancer-inducing radiation needed to properly mind control the children.

BULLSHIT. The frequency was chosen for effectiveness of generation (a very simple magnetron) and shielding, and for regulatory compliance - you don't want an oven that leaks in the frequencies that are useful for sensitive radio communications, for example. There are no sharp absorption peaks in water below 3THz. Over the range of 3THz down to 0.3GHz, the absorption decreases smoothly by two orders of magnitude. It'd downright boring. There is a slight dielectric loss peak (less than an order of magnitude's worth!) in pure water that is sharply dependent on temperature and thus is useless in heating scenarios. This is, again, only for pure water. If the water is bound, like it often is in the tissues, the frequency of this dielectric absorption peak goes down by orders of magnitude. So, let's stop with the myths.

Result was stunted growth, rotting teeth and other fun stuff that comes from severe deficiency of certain minerals. And their case is far from unique.

Frankly, I think that for all the evil that "think of the children" approach has done to the world, making children pay for obvious mistakes done by their adults should be minimized by society whenever possible. Especially when education would solve the problem easily.

The particular complaint at the time was over the erection of a base station in the vicinity of a primary school. So the existence of a base station in the vicinity of the Nokia R&D site was the perfect counterpoint.

There are logic anti-patterns two which are closely related, and quite often ovelap:
correlation implies causation
what happened after this is because of this ("post hoc ergo propter hoc")

Both are insidious. Humans are supersicious and overactive pattern-matchers. There's presently no survival disadvantage to that trait. If anything, strength through incorrect groupthink can still have a positive survival benefit (a community of fools will find things easier than a lone member of the outgroup).

Anything with potassium in it is radioactive.

"Naturally occurring potassium is composed of three isotopes, one of which, 40K, is radioactive. Traces (0.012%) of this isotope is found in all potassium making it the most common radioactive element in the human body and in many biological materials, as well as in common building materials such as concrete."

Gee, I hope the "parents" never find out. This is real radioactivity, not the wussy WiFi sort.

I remember when cellphones base-stations were being maligned as being totally cancerific (that's a mother-of-schoolchildren science term), the response to a "there's no connection, all published results say so" claim by the big companies was "therefore they're not publishing the stuff that proves our claims - it's a coverup" from the anti-sciencoids (that's a worked-for-a-basestation-manufacturer mild insult).

These mothers were unable to explain why the local Nokia R&D site had a massive base-station *right in the middle of it*, and how that would fit in with their consipiracy coverup theorem.

You can't argue with idiots whose minds are already made up using *any* language.

No kidding. Case in point:
My grandfather stood (with many other soldiers) in front of microwave radio transmitter directed cones (dishes) to warm themselves up in subzero temperatures. They didn't really wonder how or why it worked at the time.

Guess how many died from cancer as a result? Out of a group of 30-something guys, 10% died from *A FORM* of cancer.

Re:Wouldn't someone think of the children?

Is it an accident that microwave oven frequencies are really close to WiFi? No. Yet older color televisions also emitted Xrays. And lots of basements emit radon. Older watch dials glowed nice and radioactively.

Let's consider the facts:

A microwave oven has over 500w, often much more. WiFi? Limited to a skinny watt, often less.

Older color TVs emitted xrays-- out the back and bottom. Unless you put it in your lap for weeks at a time, not much exposure.

Basements in some areas do have a lot of radon. Oops, this one's real and needs to be dealt with through the use of radon detectors and remediation.

Finally, those old watch dials that glowed in the dark indeed had mild radioactivity.... about as much as ten minutes in the sun.

Re:Wouldn't someone think of the children?

Most schools in NZ already are wired for ethernet, since before wifi was a thing. The simple approach (outside of dedicated computer rooms) is to put the computers on benches along the wall on one side of the room, leaving the rest of the room free to rearrange as the teachers see fit.

A better solution more generally to putting computers in the middle of a room is to use overdrafts suspended from the ceiling to deliver power and data cabling to desk clusters by vertical conduit drops. These are either hidden above the false ceiling, or in many places, they take the naked-building approach, and suspend them from the exact same overdrafts and cable trays they would use in a false-ceiling approach, but neglect the false-ceiling. This has aesthetic advantages, by providing a high ceiling, leading to a feeling of openness, and is appealing to tech companies like Facebook or Vodafone along the lines of "yeah, we're a tech company, and what?"

Re:Wouldn't someone think of the children?

[redlemming]

If you want to talk about safety, arguments from broad classes of things that have some nominal commonality are painfully useless. If you aren't at least introducing concepts related to dosage, population level statistical study, various epidemiological techniques, you are basically just waving your hands from first principles.

You make some excellent points. An additional point comes to mind, and I apologize if it seems like hand waving ...

In the study of frequency dependent systems we often don't understand all the possible non-linear ways in which a given system can respond. As you mention, any system interaction with electro-magnetics is necessarily frequency dependent. It isn't clear to me how one would construct a medical study to take possible non-linearity of response into account.

In other words, a study might inject a signal at a particular frequency (yes, we can only approximately generate particular frequencies, but let's neglect that point) into living tissue, then vary the frequency to observe penetration depth as a function of frequency. But what if multiple frequencies are present at the same time? Might the system behave differently under some combination of signals than we would expect from the superposition of responses to the individual inputs?

It would seem that it would have to, since no real system is actually linear.

In medical studies of exposure to electro-magnetics, they are certainly exposing living tissue to some signal or combination of signals.

The question that then comes to mind is, what if the studies aren't generating the right combination of input signals to see a response that might indicate a problem? One could potentially do a lot of population studies without realizing that the inputs are wrong in every one, because we've made an unwarranted assumption regarding system linearity.

I think it's unlikely that any combination of low amplitude inputs would pose a problem, but who can be certain?

It seems like we would want some way of proving that any possible non-linear effect that can result is necessarily non-harmful.

Never mind that when you do such experiments, you remove all unimportant factors. This means that you sure as heck shouldn't be using off-the-shelf equipment. You get a radio test set to generate a WiFi test pattern of some sort, run it through an amplifier, and dump it into a radio-tight environmentally controlled enclosure with the plants. You then vary the power over 5-6 orders of magnitude to see if it really matters. That'd be experimental method 101. And all of this stuff could be had reasonably off eBay, probably for under $1k shipped if you're willing to wait a couple of months. But you need to fucking know what you're doing. No, a bunch of 9th graders and their clueless teacher probably won't cut it.

Parents being rational about their children?

Most world religions call for 'love of the neighbour as yourself'. However all who have children should hear 'love your neighbour as your child', as in practice parents are not good at being rational about when their children are concerned, with the result that we see children locked up in doors in reaction to 'stranger danger' - and thereby, overall, suffering more damage from lack of exercise and social interaction.

Re:radiation and cancer

You're confusing the difference between knocking an electron loose through sheer force (ionizing radiation) and simply exciting an electron to a higher energy state before passing it on (photosynthesis).

The difference is, if there were nothing for chlorophyll (or insert-pigment-of-choice-here) to donate it's electron to, nothing would happen to it. The excess energy would probably just be absorbed as heat, and you'd still have boring old chlorophyll. But, hit it with enough ionizing radiation and you can damage the molecule enough so that it's no longer boring old chlorophyll. And that's what causes super-powers.

Re:radiation and cancer

[lxs]

A red light photon carries about 16000 times the energy a photon from E.M. radiation @ 2.4 GHz carries. That difference is comparable to the difference between red light and hard X rays. Light from the indicator LEDs on the router has more chance of hurting you than the waves from the antenna.

High pitched noises

[RogueyWon]

I wonder how much of the occasional health panic that springs up around wifi - and indeed other technologies - can actually be attributed to the high pitched hums that can be emitted by badly manufactured devices.

For instance, when I moved home last year, my new ISP - Virgin Media - provided me with a router when I signed up with them. Their "superhub" - basically a rebranded mid-range Netgear home router - shipped with a cheap and nasty plug adapter, which was prone to emitting a high pitched squeal. Google will turn up plenty of forum threads on the issue if you're interested. Anyway, because it was right on the edge of my hearing range, it took me quite a while to work out what was going on. Until I did, I suffered several weeks of sleeping problems, headaches and nausea - pretty much the typical symptoms associated with cries of "wifi is harming my health". Swapped the plug adapter for a better made one and everything was fine.

Now admittedly, I've always been sensitive to these things. When I was a teenager, my dad had a job that meant that there were often medical devices (monitors, defibrilators etc) used in training course in the home. One weekend he had brought home a monitor device that emitted a particularly horrible hum and left it switched on for testing. Nobody else in the family could hear it, but it made me quite violently ill. He refused to believe that I could actually hear anything until I talked him into a blind test where I went into another room and then shouted "on" and "off" as he toggled the power on the device.

So yeah... while schools should be pushing back on the idea that wifi can harm childrens' health, I do think a lot of them might want to check whether any of their electronics are giving out high pitched squeals like that (particularly as childrens' hearing tends to be more sensitive to these ranges).

Re:High pitched noises

Hmm. The odds are this is psychological in nature - more akin to hypochondria than a direct physical effect. If I put an inert device in a kid's room and said it was a slightly radioactive or a very poisonous insect killer, I'd wouldn't be at all surprised at some sort of physical manifestation of anxiety. Then there's the reinforcement - as you hear certain sounds, you are anticipating symptoms, which inevitably manifest. It's a Pavlovian response. Radio waves and wind farms are just the adult version of this. I wouldn't rule your experience out - there are interesting effects on the brain with binaural beats, etc. - but there's a lot of pseudo-science out there too.

A TV show once made a 30-minute documentary about one such lunatic. The one thing they didn't do, the first thing I thought of when watching the crap, was to put him into a room shielded from outside influence with a device that has its power-on button disabled, or is hidden, or whatever, and have him tell them whether it's on or off. Repeat 10 times. Might take an hour or two, but they followed him around for at least a day for the rest of the bullshit, so that shouldn't matter.

Yeah, I've noticed that as well whenever the subject comes up. If pressed, the "sufferer" will usually come up with some reason as to why the test wouldn't be valid.

In my case it was much simpler. The device was either making a loud high-pitched noise or it wasn't and I didn't want to prove a point or get sympathy, I just wanted it switched off.

Oh, my other bug-bear... those "teenager repellant" buzz devices that some shops have used to prevent teenagers hanging around outside their store (on the basis that teenagers have a higher hearing range).

The "classical music" alternative is far more civilised.

Re:High pitched noises

[Anonymous Coward]

We have cross-country power lines a quarter mile off. They are sometimes annoying because they have some chirping/buzzing noise. Of course, that's not the electricity you hear, but some line that is mechanically in resonance because of a bad length/tension combination. And it is the current that does it: the chirp is pretty independent from wind conditions. Of course, it doesn't help that we are basically at right angles to the lines, so the effect is that of line radiation rather than point radiation.

No idea about the electrical field. But the damn chirping is annoying. Since the lines and the accompanying power plant are rather new, I guess I'll complain soonish. No idea what the effort for fixing this would be.

Re:High pitched noises

When people complain of health effects due to wifi, power cables, or other things they don't understand they should be taken seriously, despite the fact that these technologies have no scientific reason for causing those effects.

They want to kill bushes and trees for access and to prevent trees from anywhere near to the high voltage lines.
The grass (what you saw was weeds, btw) grows back first and fairly quickly.

Also, in addition to herbicides, I would bet that some unscrupulous companies got rid of their PCB's and contaminants by spraying them under the HV right of way.
In places where that was done, you may see clusters of the diseases associated with those chemicals; in other places not. If someone made a study of the cluster and said "It's due to radiation from HV lines", the company is unlikely to say "Nope, that's actually because we dumped our toxic waste there."

Yes, we know power lines cross farmer's fields. We also know that the power company does not have to get rid of trees in farmer's fields because the farmer does that. It's why they're called "farmer's fields" and not "farmer's forests".

I can 'hear' it, the same way I can 'hear' the highest pitch of a variable sonic pest repeller (rather more as pressure than as sound). I expect the nausea effect is because it impacts the inner ear, thus balance.

However, taking such effects seriously doesn't mean every nutjob's complaints are valid. I'm reminded of incidents where people were in an uproar over a new cell tower, how it was making them sick etc., only to learn that it hadn't been powered on yet. Contagious imagination, anyone?

They spray just around the towers, so vegetation doesn't grow up the legs and short out the lines, which is expensive to fix. They don't need to spray under the lines.

In the early 1970's I worked in a machine shop. I was exposed to hand-soaking kerosene at one station, which was being used as a cheap cutting/ drilling oil. I developed small wart-like bumps. At a medical library I looked up if kerosene was carcinogenic. One book stated as a fact, that all petroleum distillates are. Another book stated as a fact that it was not, and that the whole issue of chemical carcinogenesis was 'iffy,' or unsettled. Guess which book was written by a chemical industry affiliated group?

Considering the range of different chemicals present in "petroleum distillates" (also that these can vary depending on both the original oil and the refining process) claims that they are "all X" are likely to be nonsense.

About that time I was writing for an environmental magazine. Every time the EPA or OSHA or somebody would ban a compound because it had evidence of toxicity, the users would come up with a new chemical without evidence of toxicity. Or we'd have to figure out what to do with water that was contaminated by dioxins and stuff.

I used to go to the library, and interview scientists (on both sides) and ask them, "How do you know this chemical is safe? How do you know it's dangerous? Where's the evidence?"

I was amazed to find out that for most chemicals in daily use, like the ones you could pick up at a hardware store, there was no good evidence one way or the other.

Think about it. How do you prove a chemical is safe? How do you figure out whether a chemical is dangerous? Do you feed chemicals to people and watch what happens? Do you feed chemicals to rats? Do you go back and look at medical records of people who were and weren't exposed to chemicals?

Computerized records now make it easier to keep track of what happens after occupational exposure, but still, it's damn hard to figure it out. There are a few cases where investigators luck out (to the misfortune of the subjects) and find a well-documented pattern, but most of the time it's a short-term study with a small number of (unfortunate) rats who were checked for a small number of problems.

I haven't kept up with that stuff recently. If anybody has I'd be interested in knowing what's going on.

Re:Hmmm

[mirix]

Yeah, longer straight chain stuff should be pretty much harmless, but aromatics tend to be carcinogenic, irritant, stink, etc. (though it depends on the chemical in question, it's not a rule.)

Short alkanes aren't very good either, being very flammable and toxic, but aren't carcinogenic afaik. As the carbon chains get longer they become benign (with the greatest risk being that of getting them in your lungs - hard to get out, causing some sort of pneumonia like illness).

Normal kerosene (in north america, at least), is about 15-20% aromatics IIRC, which is why it has an odor. More refined variants for lanterns don't. Same deal with (pharmaceutical) mineral oil, or vaseline. harmless, but they come from the same stock as kerosene, and they are all 'petroleum distillates'.

It's also part of what's right with just about everything nowadays.

Seriously, willingness to compromise your own wishes to accommodate others is the basis for human cooperation, which is the basis for not only not killing each other at an astounding rate (archaeological evidence suggests that pre-historical peoples had homicide rates about three orders of magnitude higher than is typical for first-world nations today), it's also the basis for all of the societal structures that enable commerce, technological progress and government, among many, many more.

I agree with you that the number of ridiculous compromises has been rising in recent decades, but that's been accompanied by large reductions in all forms of violence, including both retail and wholesale murder as well as rape, bullying and domestic abuse, just to name a few. I don't think the two are unrelated; I think both are driven by an increased willingness to "give in just a little so we can all get along", due to increased levels of empathy, and eye-rollers like unnecessarily removing Wifi are probably an acceptable price, as long as it isn't too high. In this case they're replacing Wifi with wired Ethernet, so they'll get some significant reliability and bandwidth benefits out of the change as well... and eventually I'm sure they'll put the Wifi back.

The problem I often see with people is that their emotions tend to take over rational thinking. This behavior should be shunned and held in disdain, much like farting at the dinner table. Losing your child is a thoroughly devastating experience. Since we're human, we shouldn't act like dogs who hump at the street corner because they feel like it. Just because we feel like "doing something" after a loss of a child doesn't mean we are free to go full retard.

Only if there's an absorption band.

[Anonymous Coward]

Radio waves don't just get absorbed when passing by some matter, they have to be of the right energy. It's quantum. So your radio waves will heat the WATER which has the right absorption frequency for WiFi. And your blood? That's a lot of water. So it gets heated and then moves that heat around when irradiated with WiFi radio waves.

Rather similar to your "reasoning" that light and IR is fine from the sun.

PS check the flux of gamma, X and cosmic rays that will pass through your brain and "heat it directly" and compare to the energy flux from a WiFi AP at 100m.

Re:Only if there's an absorption band.

[amorsen]

Radio waves don't just get absorbed when passing by some matter, they have to be of the right energy.

Water will absorb an extremely wide band. Contrary to popular belief, 2.5GHz is NOT a special resonant frequency for the water molecule, pretty much any cell phone band would work fine for microwave ovens. 2.5GHz was picked for engineering reasons, not out of physical necessity.

Re:Only if there's an absorption band.

Are you a radio astronomer or something? Because yeah, what you say is true on astronomic scale, it's also true in gases, hey, we're no stars no gases, right?

Radio waves don't just get absorbed when passing by some matter, they have to be of the right energy.

For real-life complex organic matter, the "right energy" is not just a few absorption peaks, it's a rather broadband spectrum. It'd be rather cool if you could use some meat from your freezer as narrowband RF filters. Nature doesn't work that way.

Using 2,4Ghz in wireless network is not harmful

[jonfr]

This is not complex, at 2412Mhz (start of 2,4Ghz wlan) does not harm you at the transmission levels used in wireless network. The transmission power is around 100mW, based on the law of square that signal fades quickly when the distance is more then 100 meters. Just if there is nothing blocking the signal. If anything is blocking the signal it fades faster and more quickly. At 5180Mhz (start of 5Ghz wlan band) the signal goes even shorter distance at the same power.

The idea that people can get sick or even cancer from normal radio bands (2Mhz to 60Ghz) is just ridiculous. It is nothing more then a chance that this boy got the brain cancer. It has nothing to do with wireless networks, mobile phones or television transmission masts (they broadcast in the 230 to 800Mhz range). Mobile phones are in the range of 700Mhz to 2100Mhz (LTE/GSM/3G). Depending on country and location.

For the sake of discussion I have simplified use of frequency band used in mobile phones and 5Ghz wireless network.

Re:Using 2,4Ghz in wireless network is not harmful

[Anonymous Coward]

You haven't discussed anything. You made some vague statements (why are those transmission levels not harmful?) and false assumptions (in school wireless networks you are almost always within line-of-sight of an access point and are always within 100 meters. Each classroom has an access point. You're normally within 5 meters.).

Re:Using 2,4Ghz in wireless network is not harmful

[jonfr]

You want facts? Here are facts for you. I don't make any guarantees that you understand those facts.

http://missionscience.nasa.gov/ems/05_radiowaves.html
http://missionscience.nasa.gov/ems/01_intro.html
https://en.wikipedia.org/wiki/Radio_wave

2412Mhz has the wave length of 124mm according to this calculator (http://www.onlineconversion.com/frequency_wavelength.htm). The size of human DNA molecule is far smaller then this. The wavelength of 2,4Ghz and 5Ghz is therefore too big to have any effect on DNA in living animals.

I will pray for them.

[oscrivellodds]

That's the only reasonable thing to do in a situation like this and it the chances of it working are about the same as removing the wifi network. Praise Jesus!

Sigh

[ledow]

I work in schools.

In one school the parents protested the installation of a mobile phone mast 500 metres from the school. They failed. While all the time we were having to remove phones from students and all the staff were wandering around with them strapped to their belts.

Then they protested our "wireless networks" (really a couple of WAP's on a trolley). While more parents complained that we didn't offer free Wifi in the reception area, and that they couldn't connect to the Internet when we had open-days.

People completely misunderstand the technology, and on the other hand also demand the services that technology provides. They also miss the point that, pretty much, vastly more "damage" is done by holding a transmitter with more power per square centimetre to their heads than anything outside the school building could manage.

Pretty much, they had petitions, the petitions were sent off into the consultation process, the mobile phone mast happened anyway, and we were allowed to "put in" the wireless networks that had been in the school for 4+ years beforehand anyway. Then all the moaning disappeared and the parents were happy because we gave them Wifi in reception.

Yeah right Mr. Einstein (not)...

[Anonymous Coward]

"For the record, the sun's heating and radio wave heating would work differently. The sun heats the surface. The sun wouldn't do a particularly good job of heating the brain. The scalp would heat up, but then blood does a pretty good job of distributing that heat around, and the skull would be a decent insulator. Radio waves would penetrate into the brain and heat it directly."

If your head is exposed to intense heat from the sun during a very hot summer day you will find the heat transfer to the blood which courses throughout your brain will indeed lead to death. I am talking air temperature of 25C+ leading to eventual death within a relatively short time period.

Re:Yeah right Mr. Einstein (not)...

[Chuckstar]

LOL... No. That doesn't happen. You can stand in the sun all day in 25C temps. You might get a bad sunburn. You might get dehydrated. But your brain doesn't heat up and fry in your head.

Hell, where I grew up it was regularly 45C+ during the day. You had to worry about staying hydrated, and about getting sunburned if you didn't have a good tan (or use sunblock), but otherwise you could be out in the sun for hours without your brain overheating and killing you.

It depends

[justthinkit]

It depends on how the antennas are aimed. They are directional after all. For example, you talk about an "old school" microwave long distance relay -- how likely is it that this will be aimed at you, the ground, etc. It is aimed, as tightly as possible, at the next relay tower.

To the direct south of me, just five houses away, I've measured levels of 24,000 microwatts per meter squared (on the sidewalk) -- one-third of the reading directly in front of a working microwave oven. Move ten feet (or one foot) over and it is "just" 2,000 or 4,000. Outside my home it is 700 and the one time I took readings north of me I gave up after a house or two -- they were in the 100 range. And yes I have an "antenna farm" just a hundred yards away, with dozens of antennas spread over an enormous retirement center roof. By the way, at the base of all that, the front door measurements at the center are just 100 to 300.

It is about are you line-of-sight, and where are the antennas aimed.

My video on the subject.

Ah

[Anonymous Coward]

They are aimable. "Broadside" radiation, if you are directly being aimed at, and just 50 feet away, can be up to 1,000,000 microwatts per meter squared whereas at the base of that same tower it will be 300. Also, the legal level for those who work with it is five times higher than for Joe Citizen. Also, how do you know they haven't suffered at least some long-term effects? Do you think that would (1) be posted on the front of the building and (2) get Nokia to stop?

Parents suck

[Nyder]

Back when I was a teenager, we had an underage night club. It was great. 2 kids, who ran away from home to hang out on the streets of Seattle, to go to this nightclub and do other things, had some parents who managed to get a group behind them, to shut down underage night clubs in Seattle. The kicker? They didn't even live in Seattle.

And after the nightclubs got shut down, and those 2 kids went home to new cars and other luxuries, what did all us kids who lived in Seattle have to do? Nothing, go hang on the streets.

Parents fucking suck.

There's something much more important here

[holophrastic]

I could care less about wifi radiation. In my mind, it's fine. But that's not the point here. There are plenty of things in this world, fully legal, regulation-approved, and with no proof of toxicity that are, in every sense of the word, completely toxic.

We've had bright and shiny paint based on uranium. A century later, we've had bright and shiny paint based on lead. We've had nonstick coatings with toxic fumes. We've had cigarettes that were thought to be safe for decades. Pesticides. Estrogyn-mimicking plastics. Countless drugs and treatments -- thalidimyde, blood-letting, witamins. Heck, even normal ordinary pollution. We've had all sorts of dangers unknown until they were known.

The point is that it takes time, often decades, to actually prove that something is toxic over the long term. Big surprise, you require a long term experiment to prove a long term result.

But that doesn't make the early skeptics incorrect when there wasn't proof. It actually makes them correct retroactively.

I'm not saying that these parents are correct. I'm saying that 100 years from now, they may have been correct. And because that's a possibility, and this is their own children for decades of schooling, they have every right to control that environment.

And that makes them right.

Embarrassing

As a kiwi - I have to say this is embarrassing at the least. However the headline is sensationalised as always.

They turned off wifi in the junior school - where more than likely there are a couple of PCs and maybe a laptop for the teacher in each classroom. Senior school - with student devices possibly - is unaffected.

I suspect this is a board doing something inconsequential to make these parents go away.

We had the same issue at a school I used to work with - years ago they were one of the first with campus wide wifi. Parents had no issue with a massive cell site 20m down the road - but a wifi access point - break out the radiation shields.

[neminem]

From the great book, Zodiac:

      My office was the size of a piano crate, but mine nonetheless. I wanted a computer on my desk, and none of the other GEE honchos would risk sharing a room with one. Computers need electrical transformers, some of which are made with PCBs that like to vaporize and ooze out of a computer's ventilation slots, causing miscarriages and other foul omens. The boss gave me his office and moved into the big barnlike room.

      The same people barely noticed when Gomez, our "office manager," started painting the walls of that office. By doing so he exposed them to toxic fumes millions of times more concentrated than what I was getting from my computer. But they didn't notice because they're used to paint. They paint things all the time. Same deal with the stuff they spray on their underarms and put into their gas tanks. Gomez wanted to paint my office now, but I wouldn't let him.
