Ontario Says “No” to Cell Phone Warning Labels

November 5, 2010 1 comment

And it’s the right call. For two reasons:

  1. There is no conclusive scientific data to support any adverse health risks associated with short, moderate, or long-term cell phone use.
  2. A warning label would serve no purpose, other than to instill fear into the users.

The bill proposed to put a sticker on all cell phones indicating that there could be an increased risk of cancer from using a cell phone. Not only is this unnecessary, but it’s also wrong.

The scientific data overwhelmingly shows that there is no increased risk of cancer associated with cell phone use.

And what purpose would a warning sticker on a cell phone serve anyway? Would any of us stop using our cell phones? Would we hold it further from our head while we talk on it?

Of course not. Eventually we would get over our initial shock and fear of the warning sticker, read all the buzz-word containing media-frenzy stories about the evils of technology, and then settle back into our normal routine. All in all, this was a bad idea to begin with.

But my oh my, look who turned up to give her opinion on this issue. Our old friend Prof. Magda Havas from Trent University. She turns up in just about every story that involves cell phones, wireless internet, power lines, dirty electricity, and many other stories trying to convince us that technology is bad.

So I want to get something straight about why she keeps showing up. Is it because she is an expert? I would argue not. Her Ph.D. is in botany (the study of plants) so I don’t see how this qualifies her to study electromagnetic fields and their interaction with the human body. The list of publications on her website has very few peer-reviewed articles. Instead, it’s littered with “Letters to the Editor” and other opinion based writing. Not a lot of scientific credibility there.

No, she shows up because media outlets try to get both “sides” of the story, even if one side is way off base. Enter Magda Havas, who is one of very few people in the world who believes in electrosensitivity and kids getting sick from wireless internet. There are so few people who think this way, that they keep going to one person on the fringe to get her opinion. It is sloppy reporting, and not indicative of the evidence.

On CSI, Grissom (who was the best character but left, and now I am sad) always tells us to “follow the evidence” because the evidence will lead us to the truth. If we follow the evidence about cell phones, we see overwhelming evidence that cell phones are safe. Why then, do we continue to read about how evil they are?

Wi-Fi the New Danger to Children…Apparently

August 16, 2010 2 comments

Well, as if we didn’t have enough to be afraid of in the pseudoscientific world, now we have to be afraid of our wireless internet connection.

Parents in Barrie and other northern Ontario towns have called the public school board to remove its recently installed Wi-Fi system because, they claim, it is making their children sick.

The symptoms include memory loss, trouble concentrating, skin rashes, hyperactivity, night sweats and insomnia.

These are extremely non-specific symptoms, and most of them can describe pretty much every young child I know at some point in their lives.

Said one of the parents:

“I’m not saying it’s because of the Wi-Fi because we don’t know yet, but I’ve pretty much eliminated every other possible source.”

Really? You’ve eliminated EVERY possible source? Thats quite a bold statement when it comes to environmental factors.

Now, its hard to blame these parents for looking out for their kids, but this is a clear cut case of poor understanding of technology and media hysteria.

Oh yes, I’m talking about YOU CBC!

For example, take the “expert” they got to comment on this story, one Professor Magda Havas from Trent University (in my hometown of Peterborough, Ontario, incidentally).

So what does this professor say? From the CBC article:

Claims by Health Canada that Wi-Fi is safe provided exposures to radiation are below federal guidelines are “outdated and incorrect,” based on the growing number of scientific publications reporting adverse health and biological effects, Havas wrote.

Havas did her Ph.D in Botany, so what makes her an expert electromagnetism, I have no idea. But from her website (note the advertisement to her book at the bottom), it seems she is involved in fear mongering for just about every junk science theory about electromagnetism affecting humans, including the dangers of power lines and cell phones (all these technologies have repeatedly been shown to be safe).

It amazes me that they couldn’t find an actual expert in electromagnetism to comment on this story. But then, it wouldn’t increase readership would it?

But shall we interrupt this exercise in bad science and bad science reporting for some REAL science?

The energy deposition from a typical wireless signal is roughly 100 times less than exposure to a cell phone (which remember, has been shown to be a perfectly safe level). It is also thousands of times less than current government regulated safety levels, AND is less than normal background radio frequency radiation. Maybe that rat-bastard Ryan Seacrest and his Top 40 crap is making us all sick!

Now how about a bit of logic? The parents claim that these symptoms go away on the weekends. This makes no sense as children are exposed to wireless signals at their home, at the mall, the airport, restaurants, pretty much everywhere. If it was the Wi-Fi and these children are truly sensitive to it, they should be sick virtually all the time.

And what about children living in an apartment building, where there are literally dozens of wireless signals in their vicinity. Shouldn’t they be affected at home as well? Shouldn’t this be more widespread?

Ok, so when I start freaking out about stuff like this, my lovely girlfriend invariably asks “So what COULD it be, if not the Wi-Fi?”

My Lovely Girlfriend. Yes, I have one!

Well, remember these symptoms: trouble concentrating, hyperactivity, insomnia, night sweats. This sounds like me when I was a kid. I was always having trouble sleeping and running around like a madman. These tended to go away on the weekend though, when I could just relax and play video games. Also, kids don’t like school; they could get stressed out and cause these symptoms, which would of course go away on the weekends and in the summer. They may be staying up too late on weeknights, so sleep deprivation could easily cause some of these symptoms.

Want to know what I really think is happening? I think a child got sick with something, and an over-zealous parent read something about Wi-Fi being dangerous on the internet. They heard that the school had recently installed Wi-Fi and BAM! you got yourself the perfect storm of fear.

If you take nothing else from my blog, please take this: Correlation does NOT equal causation.

Just because these children got sick after (several months after, which is kinda weird. Shouldn’t they have gotten sick right away?) the school board installed wireless networks, does NOT mean wireless networks made these children sick.

I could just as easily say the sun rose after my alarm clock went off this morning, therefore my alarm clock caused the sun to rise. It is a logical fallacy and stories like this are riddled with them.

So don’t worry folks, your internet is just fine. Continue using your laptop (to read this blog, hopefully) and your cell phone without fear. With every new technology there will be those who try to convince you its bad. And unfortunately, there will also be protective parents to make a fuss over it.
