# Ontario School Bans Wi-Fi

#### samzenpus posted more than 3 years ago

287

St. Vincent Euphrasia elementary school in Meaford, Ont. is the latest Canadian school to decide to save its students from the harmful effects of Wi-Fi by banning it. Schools from universities on down have a history of banning Wi-Fi in Ontario. As usual, health officials and know-it-all scientists have called the move ridiculous. Health Canada has released a statement saying, "Wi-Fi is the second most prevalent form of wireless technology next to cell phones. It is widely used across Canada in schools, offices, coffee shops, personal dwellings, as well as countless other locations. Health Canada continues to reassure Canadians that the radiofrequency energy emitted from Wi-Fi equipment is extremely low and is not associated with any health problems."

back@u This again makes no sense as the minute the students get home they are surrounded by Wi-Fi all around them from their neighbors. I myself when looking for open points sitting on my couch will get between 20 - 30 and 10 of them are at least 60% strong. We're swimmin in it everyday so who cares.

Well, we should not simply block the sun. We should switch it off.
* It runs on nuclear (fusion) power.
* It is responsible for many cases of skin cancer.
* It is the power source for hurricanes, which cause lots of damage.
* Its radiation plays a major role in the chemical processes which cause the ozone hole.
* It is already known that one day it will destroy the Earth.

Thing is, even if we did we wouldn't see the effects for the best part of a million years. The reactions at the heart of the sun take a long time to make their way to the surface, what with there being lots of density and that. It's going to be a long running battle, it'd probably be quicker to evolve wide spectrum shielding skin...

Uh... it's a bit unclear if you're understanding the situation here.

"If my doctor was that stupid I wouldn't listen to them either."

If your doctor were how stupid? The only mention of doctors here is that the doctors say there is no medical basis for a ban. Based on the rest of your post, surely you mean to criticize the people who ignore the doctors' advice and ban WiFi anyway - which is exactly what GP said - right?

Oh, and for the record, doctors do advise strict limits on sun exposure now. That's what sunscreen is for.

Chiropractic health professionals either deal with the skeletal system or with bullshit. Some of them you walk into the office, they know everything about all ligaments, tendons, joints, bone structure, etc; and they can throw you under an X-ray and point out all the stress points from your posture and all long-term damage done from you always sitting wrong. They can also supply physical therapy, nudging the joints here and there to straighten things out that have gone a bit awry.

The bullshit artists are the ones that want you to believe all ailments are cured by chiropractic practice, which the parent seems to be.

I beg to differ with you. I've been to a few chiropractors over the years on strong suggestions of my friends. I did it mostly to shut them up.

Apparently my back is invincible (except for the chronic pain). They can bang, jump, and pound on my upper back, and nothing happened. Well, after a while it ends up with me saying "If you don't stop that, I'm going to get up and kick your ass."

My neck is pretty close to the same.

I don't think I'm that much of a tough guy, but I think I'd hold my own with a bunch of doctor wannabe's.

I shouldn't talk too much shit about them. I considered doing it. 6 months of night school, and then you get to call yourself "Doctor" and horribly overcharge patients *AND* get them to come back twice a week after that. :)

This may, in fact, be a rational decision by the school's administration. While the health dangers due to wifi may not be real, the (often irrational) fear that some people (e.g. parents) have of wifi is, unfortunately, very real. If enough people are sufficiently afraid, and their fear is causing a great deal of difficulty, banning wifi may be the most straightforward solution, especially if wifi isn't mission-critical for that particular school.

Indeed there is, in fact I believe there are 2 of them. Mind you they only protect against a few varieties of HPV (with some overlap between the two I believe) but the ones covered include the ones that have the greatest chance of causing cervical cancer.

These vaccines have only been tested on women (no reason to believe they don't work on men, but last I checked that was off label) and your insurance generally wont cover the vaccine if you are over a certain age.

Sure, no reason to give the vaccine to 2 year olds, but kids get sexually active fairly early in life and cervical cancer is pretty bad, so why not vaccinate. I know if I had daughters I would have them vaccinated.

Obviously not, and there's a certain level of sarcasm there. But the underlying point is valid - you don't want to make decisions just because the irrational minority makes a lot of noise.

In this case it's probably not worth dealing with them over something as insignificant as WiFi, but figuring out when something is important enough to fight for is the difficult question.

Of course banning wifi is silly but I applaud the school for listening to the majority of the parents. I just wish local schools allowed parents so much control over what the schools do, pretty sure parents wouldn't have voted to allow the school to spy on students through webcams

I have to question that article. I spent quite a bit of time in the Meaford area, and while the locals might not be the smartest folk in Canada, they're not a pack of knuckle-dragging troglodytes, either. As a gut-reaction, I'd say it's much more likely that the PTA is either lying through their teeth, or when they talk about "voting" they're referring to the 5 or 6 yokels who happen to show up for PTA meetings rather than the populace as a whole.

Yes, the most important lesson a school could teach is the proper response when ignorant of something, is fear, and the ignorant fearmongers position makes them morally superior to all others thus we must subject everyone to the tyranny of the (ignorant) minority.

Sure, it's normal to ban something if it's been proven to be harmful, but I can't think of anything that hasn't been banned because there's no proof that it isn't harmful.

Part of the problem with that is that everybody seems to want to start with the position that "this is safe unless you can irrefutably prove otherwise", and they go ahead and load everything up with chemicals/whatever and assume it's safe. Which does lead to stuff that you might expect to be dangerous being used until someone can prove it is dangerous. Pharma companies do it all the time, and, have been proven to have lied about risks they knew were there. Think Thalidamide, for instance.

I don't always trust people when they say "oh, sure, this radioactive corn with spiders-silk genes must be perfectly healthy there's no proof to the contrary". The companies introducing these things want us to believe that their chemicals are safe, but it's all discovered after-the-fact.

Assuming everything is safe generally leads to companies pursuing profit with absolutely no regard for if their product is safe. Then they get the rules changed so they're not actually required to tell you about what's actually in it because it hasn't yet been proven to be a possible risk. I wouldn't trust Monsanto on any claims they make about product safety, and I think that to a certain extent, companies should be doing more testing before they release it to the market.

You can go ahead and eat the experimental green goo -- personally, I'd rather they had to put it on the label so I could choose, instead of just saying that it hasn't been proven harmful. It's too damned late by the time they 'discover' that a something we've never tested is, in fact, dangerous.

As usual, Health Canada gets it wrong.

It's not that the signal is low energy, it's that the radiation is not at a frequency that can do any damage.

They could boost the power to the point where it boiled the water in your cells. That's what it would take to do damage, because the wavelength is too long to break chemical bonds. That's the neat thing about quantum mechanics; if one photon can't do any damage, neither can a thousand photons.

They didn't get it wrong. Their statement is perfectly correct. It's also more relevant than your reason.

Ionizing radiation doesn't give you headaches and inability to concentrate that goes away on weekends. Exposure to RF at microwave oven, heating-up-your-brain levels could do so a lot more plausibly than ionizing radiation.

Hmmm, not really. Most peoples brains are very well provided with blood vessels. Good luck cooking a living mammal brain.

On the other hand, your eyes cornea has very little cooling capacity. Its not difference of a few percent, its a difference of a couple orders of magnitude. Cooked corneas are not transparent, as a generation or two of radar repairmen accidents have unfortunately proven.

Blasting enough RF to cause heatstroke like effects to the brain over a long term period, are almost certainly high enough to cause instantaneous permanent blindness.

E = h \nu "It's not that the signal is low energy, it's that the radiation is not at a frequency that can do any damage" Given that you say "boost the power to the point where it boiled the water in your cells" I think you're confusing power, i.e. energy per second (and power density at that, i.e. energy per square meter per second) You get it right, though with "if one photon can't do any damage, neither can a thousand photons." You can heat with it, though, by exciting motion in e.g. polar molecules (and these are dependent upon frequency as well, since molecules "like to" move (i.e. are resonant) in different ways (different modes) and at different frequencies, hence the FCC power recommendations for ham radio even for wavelengths that are large compared to parts of your body). So you can make up for a lack of efficacy (i.e. by being off-resonance) by throwing more power at it (unless, of course, the molecule is completely non-reacting).

To be fair, their goal is not necessarily to get it right, but to reassure the populace that it is safe and keep them from panicking. Now, whether this is a laudable goal is questionable, but I think that's what they're doing, and an accurate explanation might actually detract from that.

E = h \nu

"It's not that the signal is low energy, it's that the radiation is not at a frequency that can do any damage"

Given that you say "boost the power to the point where it boiled the water in your cells" I think you're confusing energy (h \nu where nu is the frequency) and power, i.e. energy per second (and power density at that, i.e. energy per square meter per second)

You get it mostly right, though with "if one photon can't do any damage, neither can a thousand photons." You mean breaking bonds, not heating damage. I.e. it's not "ionizing radiation".

Even if it doesn't break molecular bonds by being off-resonance, you can heat with it by exciting motion across the whole molecule in e.g. polar molecules like water (and these are dependent upon frequency as well, since molecules "like to" move (i.e. are resonant) in different ways (different modes) and at different frequencies, hence the FCC power recommendations for ham radio even for wavelengths that are large compared to parts of your body). So you can make up for a lack of efficacy (i.e. by being off-resonance) by throwing more power at it (unless, of course, the molecule is completely non-reacting). So you won't get cancer from it, but you can burn yourself by handling an antenna while it's transmitting or by being too close to one (power density falls off as 1/r^2, so being sufficiently far away is perfectly acceptable and thus why hams can be required to put up fencing to keep people away from antennas).

Of course, wifi transmitters are under 100mW (I think that's the upper limit I've seen) so you can calculate the number of photons being emitted per second, and thus how many photons are being received per second per square meter at some distance from the transmitter, using E=h \nu and the various formulas introduced implicitly above).

>>>the wavelength is too long to break chemical bonds

So how long are WiFi's waves? And how "short" do they need to be to cause damage?

Aside - It's somewhat ironic that Shortwave Radio is called "shortwave" when the waves are actually much longer than the waves used by AM, FM, or TV.

### health effects. no. education effects, definitely (2, Interesting)

This comment was hidden based on your threshold setting.

#### Sir_Sri | more than 3 years ago

While the health argument is nonsense, there are a lot of very good reasons to ban wifi in public schools. If the school doesn't have a laptop policy then the students probably shouldn't use them, too much to go wrong, both on a support end and on the student effectively using the tools side of things. I went to both public and highschool in ontario, admittedly, quite a few years ago, but there wasn't really any time except maybe lunch that we would have had anywhere suitable to want a wifi connection anyway. You were either in class, and supposed to be paying attention to the front of the room, or on your way home. And if you actually needed internet access for something legitimate, well there were lots of computers around you had access to. Installing and running a wifi network if it doesn't fit with how the school operates seems unnecessary.

This school in question only goes to grade 6 it looks like. I sort of think that 10-11 year olds probably shouldn't have laptops at school, or smartphones or any of the other modern wifi connected gadgets which sap attention and productivity from the rest of us. They aren't really ready for that responsibility, both in value of stuff or in time management. Highschool might be different, but in public school you get a couple of 15 minute breaks, and some time at lunch, otherwise you aren't supposed to be there. In grade six they're still learning to measure angles with protractors and learning to guess the meanings of words they don't know (source: http://www.edu.gov.on.ca/eng/curriculum/elementary/grade6.html) . Looking up angle on wikipedia and finding formal definitions using trig functions seems like it's probably going to do more harm than good. Even if you want to argue a grade 6 kid might be ok with a laptop, grade 4 and 5 are pretty young to be using wireless devices on their own initiative.

On top of all that you get into issues of what has access to the network, and how do you enforce that policy, and if you're going to provide access how do you make it fair for students without the financial means to get laptops etc.

Like I say, in a school that only goes to grade 6 it's a bit different than the usual primary schools that go to grade 8 or a highschool or the like. 8 and 9 year old kids are still learning to write on lined paper, they aren't really ready for constant internet access, and by the time they are, they aren't at this school anyway.

It sounds like they're using wifi as a shortcut to hook up the lab computers. No need to run a zillion cables, just drop a wireless router in the lab somewhere.

Having once wired my high school with ethernet, it actually sounds like an excellent idea. Even better when you consider that the ceiling tiles in my high school were made with asbestos.

lets say you want to give every classroom in a school a computer. You can either run cable to every classroom and set up multiple drops so the computer can be in different places, or you can blanket the entire school in a wifi network.

Now sure, some schools had wires in place from before wifi was common, but if you were trying to retrofit an old school wifi would probably look pretty appealing.

I think the fear of wifi and just anything generating signals or god forbid magnetism is worse than the actual effects of it.

What about all the satellites beaming down radio waves at GHz frequencies? surely that does some harm? who's for a tinfoil umbrella?

Anti-scientific 'ban everything' movements are the flipside of the pro-CO^2 believers. People who think they intuitively know more than those who study that field in particular who have research to back up their claims.

It's a failing of our education system that more people don't understand science, the concept. You don't need to understand all the branches of science. You just need to know that 'my kid complains of headaches at school' does not mean you can pin the blame on WiFi without any further tests.

Ok, at risk of defending jackassery, I gotta respond to that. "push non flouridated water on us"? Water isn't naturally flouridated to any reasonable level, the flouridation is added. It's flouridated water that is being "pushed" on people because they're not give the choice. It may be well below the level of toxicity, but asking to not be exposed to a toxic chemical just because some people refuse to brush their goddamn teeth isn't exactly a radical position.

To all the people who doubt there are people sentive to radio frenquencies, you would feel different if you could barely go outside without being bombarded with headaches. Its beyond me why there are idiots out there that think that if it dosent affect them, its perfectly safe.

If this was any other tech, one which has been thrown around with no real research for health effect like wifi, there would be a public outcry. But since the people whos lives it ruins are a small number, people dont care.

As far as I am concerned, if you dont know how these things affect people you need to pull your head out of your ass.

### Laptops give off major EM radiation (1)

This comment was hidden based on your threshold setting.

#### presidenteloco | more than 3 years ago

Right now the health effects of various kinds of EM fields or various kinds of modulations of fields,
if those health effects exist, appear to be below the threshold at which
our current population health studies can reliably detect the correlations or
causal effects.

So we are left in the uncomfortable position of saying "we don't know", and we don't even
have any well-founded probabilistic guesses.

When you are in a "we don't know" state about some purported causal connection, you either
have to study it more, with better and larger, and more expensive studies, or you have to just
live with a "we don't know" state.

The problem with "we don't know" states is that literally, your guess is as good as mine.

So here we have a case where there are clear benefits to a technology, and no proven health impacts,
but some people have concerns. If I were those parents, I would be much more concerned about
sugar & simple-carbohydrate poisoning effects of the kind of food and drinks the students are probably
consuming in and around school. That's something we can prove is going to kill a lot of them before
ripe old age.

I say lets do an experiment. We'd have to be somewhat deceitful but lets get these people who are 'allergic' to RF into what we tell them is a RF quiet room. We could even employ props to make it seem as though it were. But the reality, we can bombard the room with RF while we have them fill out a questionaire on how they feel vis a vis RF illness. Betcha that they'd be hollering for joy that they're in an RF free space.
