New York Post: Sloppy Journalism in Report of Cellphone-Cancer “Link”

Posted by mattusmaximus on October 26, 2009

In another media *facepalm* moment, the New York Post is reporting of a supposed “link” between cellphone use and cancer…

Study: Cell Phone Cancer Link

A groundbreaking, $30 million study into cell phones has found a link between long term use and brain tumors.

The World Health Organization is about to reveal that its decade-long investigation has found the devices can lead to cancer — and the internationally-respected body will soon issue a public health message with its findings, London’s Daily Telegraph reported today.

The conclusion goes against years of assurances by cell phone companies and scientists that cell phone use is safe.

But last month, Sen. Arlen Specter (D – Pa) organized Senate hearings to examine health implications of talking on-the-go.

CAN YOU KILL ME NOW? -- A groundbreaking, 10-year study will show that long-term cell phone use can lead to brain tumors.

CAN YOU KILL ME NOW? — A groundbreaking, 10-year study will show that long-term cell phone use can lead to brain tumors.

The WHO’s Interphone investigation’s results showed, “a significantly increased risk” of some brain tumors “related to use of mobile phones for a period of ten years or more,” the Telegraph reported today.

The study’s head, Dr. Elisabeth Cardis, said, “In the absence of definitive results and in the light of a number of studies which, though limited, suggest a possible effect of radiofrequency radiation, precautions are important.”

The project carried out studies in 13 countries, talking to tumor sufferers as well as healthy cell phone users, It interviewed 12,800 people.

The results will be officially published before the end of the year, according to the Telegraph.

This is a perfect example of how some in the media misuse science to make headlines, while at the same time spreading misinformation.  Notice that the article is citing research which hasn’t even been published yet! So, if the research isn’t yet published for scrutiny, how in blazes do the morons at NY Post know what the research says?  I always thought that a good journalist was supposed to check their facts before reporting a story, not the other way around.  Apparently, the folks at the NY Post live in an alternate universe.

In addition, some other tidbits that pop up in this article:

Website Rates Best & Worst Cellphones… by Radiation Output

Posted by mattusmaximus on September 28, 2009

While cruising around the Internet I stumbled upon this website over at Engadget.com where they ask people to rate their cellphones – by the amount of (spooky word here) RADIATION output!

The irony here is the fact that a website which seems to advertise itself as tech-savvy would appear to embrace such a stupidly pseudoscientific concept as cellphone radiation being dangerous.  As has been outlined repeatedly in the scientific literature – as well as in my Electromagnetic Fields & Cancer Myths blog entry – there is NO danger from cellphone radiation… none!

As for the Engadget article, note the scale they show and the subsequent commentary…

You’re surely aware that your cellphone bleeds radiation into your face the whole time you’re on the phone with your mom, best friend or lover, right? Yes, it’s a fact we try not to think about most of the time, but now there’s a tool out there on the internets for the more reality-facing folks among us. The Environmental Working Group’s launched a website dedicated to rating cellphones on their radiation output alone. Ranking highly (meaning they put out the lowest levels of radiation) are the Motorola RAZR V8, and AT&T’s Samsung Impression. In fact, it seems that Samsung is cranking out the healthiest phones these days! Phones with poor showings includes T-Mobile’s myTouch 3G and the Blackberry Curve 8830. So hit the read link and tell us, how does your phone rate?

The scale leaves out one important fact… that all of these phones likely operate at the same frequencies of radiation.  The only thing this scale is studying is the intensity, which is entirely different!  For example, the frequency of a photon of electromagnetic energy is what determines how energetic (and therefore how dangerous in the context of causing cancer) the radiation is.  Low-frequency radiation like that from cellphones simply cannot cause cancer, as far as we know, because it is nonionizing radiation. The fact that these goofs at Engadget.com can’t even get this basic bit of physics right will ensure that they won’t be getting any of my business.

I don’t know about you, but I know how I’d rate this website for scientific validity.  I give it a rating of FAIL.

Electromagnetic Fields & Cancer Myths

Posted by mattusmaximus on April 2, 2009

Every year when I teach my students about electromagnetism, I take some time to discuss with them the physics of electromagnetic waves (a.k.a. “light”). EM-waves go by another name common to scientists, electromagnetic radiation, and it’s that second word – radiation – which scares the hell out of so many people and makes them vulnerable to all manner of woo.

Case in point, there is a lot of bunk out there concerning EM-radiation and cancer. Specifically, there is a group of folks who try to push the idea that cell phones, power lines, and wi-fi are emitting radiation (called EMFs, or electromagnetic fields) which will give people exposed to them all manner of cancers. I’m here to tell you that this is just plain b.s. – people who make these pseudoscientific arguments do not understand the physics of EMFs, at all.

First off, the physical mechanism which creates an electromagnetic wave (or “EM-radiation” or “light” or “EMFs” – they’re all the same thing) is basically wiggling an electric charge back and forth. This process generates a self-reinforcing set of electric & magnetic fields which form the wave, and the frequency of these waves (which matches the frequency at which the charge is wiggled) is what determines exactly what kind of EM-radiation is created. Depending upon the frequency of the wave, it will fall along what is called the electromagnetic spectrum…
