Be Afraid of Your Wi-Fi! Be Very Afraid!

September 1, 2010 Leave a comment Go to comments

Wow. I cannot believe this is still in the news.

Its one of those things you hope only happens once and you never hear about it again. Like the Star Wars Holiday Special.

But unfortunately, the Wi-Fi hysteria remains in the news. This time with a couple of new foot soldiers. They include a drama teacher from Brock University, and a self-proclaimed specialist named Barrie Trower.

And perhaps I shouldn’t be surprised, but the reporting of this story in the CBC is really starting to irk me. Lets explore shall we?

I wrote previously about the parents in Simcoe county in Northern Ontario were claiming that Wi-Fi was making their children sick. The supposed dangers of Wi-Fi has been dismissed by teachers, the World Health Organization, Health Canada and scientists worldwide; as it should be.

But proponents of the evils of technology continue to drag the story out and spread fear throughout the community. With a little help from their friends, the news media.

Take, for example, this audio clip of an interview on CBC with Barrie Trower.

Barrie Trower on CBC Metro News

Trower claims to have worked for the British military in the 1960s on experiments dealing with low-level microwave radiation. He claims that they caused adverse health effects; everything from affecting the blood brain barrier to the immune system. He is quite vague and never explains what frequencies or power levels of microwaves he studied.

A couple of my favourite quotes from the audio file are these:

I have a document here…it lists all of the illnesses that  children and adults can get from very low-level microwave radiation. And it specifically says on the top…this must be kept secret…the ordinary general population must not be told because it will affect industrial profit.

What is this document? Who wrote it? There are no specifics given about the origin of this mysterious document. Trower claims he gets it from the freedom of information act, but if that were true he should have given us the specifics so we could look up the document for ourselves. I am skeptical…

When I saw Wi-Fis being put in schools at the same powers and the same levels that were used in the 1960s for experiments, I knew straight away that there were hidden dangers to the young children.

You knew straight away, did you Mr. Trower? What about when Wi-Fi was being put into offices, Universities, laboratories, airports, and coffee shops? Did you not think there was a danger then? It seems interesting to me that only when the story about the Simcoe area parents came out, did Mr. Trower decided that he should reveal to everyone about the secret 50 year old experiments that he did with microwaves.

Nor has Mr. Trower provided and clear arguments or evidence (at least, to the news outlets) that Wi-Fi poses any sort of threat to anyone.

And what about the other British scientists that performed these experiments? I find it odd that they all wouldn’t want to come out and save chidren’s lives if they thought that Wi-Fi was dangerous.
While the interviewer sounds slightly skeptical, he fails to ask the right questions to point out the weaknesses in what this man is saying, so thats YOUR fault CBC.

Now lets move on to the drama teacher from Brock University, one David Fancy. Said Fancy,

It’s not necessarily up to me to say that they cause harm. I think there’s a lot of evidence to suggest that they do. But we certainly can’t say with any conclusive level that they’re safe.

Actually David, yes we can. There is a large body of literature which has studied and reported the effects of exposure to microwave radiation. The conclusion is that at the frequencies and powers associated with cellular phones, cell phone towers and Wi-Fi, the exposure level does not pose any danger.

In fact, 1 years worth of exposure to a wireless signal is roughly the same exposure as you would get in a 20 minute cell phone call. And in a recent large scale study, the long term effects of cellular phone use has not shown any mal-effects over the past 10 years.

Now, just to be fair, there is a small smattering of studies which suggest a health effect from low level microwave exposure, which these fear-mongerers can spout of the top of their heads. However, one has to take into account the entire volume of literature, not just a few isolated studies (most of which have had their conclusions contested).

You see, when a subject is studied as much as RF radiation, there is bound to be some random noise in the results of individual studes; particularly if the studies involve small sample sizes. This is completely expected. What is important is what the overall picture of the studies is, and that picture is that Wi-Fi is safe.

You can all relax now.

This all would be clear in the news stories, if the news outlets bothered to get an actual expert opinion. Why haven’t the CBC gone and interviewed physics Professors or doctors or biologists or RF engineers? Doesn’t this seem like an obvious thing to do?

Apparently not, and its having an effect. On a CBC poll about 1/3 of parents are concerned about Wi-Fi and its health effects. Kudos CBC on causing fear in these parents minds.

Sadly, talking to Physicists doesn’t boost ratings (unless maybe its Phil Plait) so we won’t get those opinions in the news. You have to go and search them out yourselves.
