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.

Conspiracy Theorists Gear Up After Release of Oklahoma City Bombing Video

Posted by mattusmaximus on September 28, 2009

Recently, the FBI released some video footage from cameras in the area around the site of the Oklahoma City Bombing on April 19th, 1995.  The video came from a variety of cameras from sites surrounding the Murrah Federal Building, the target of the bombing.  And, true to form, conspiracy theorists have already jumped all over the release of the videos…

Attorney: OKC bombing tapes appear edited

Long-secret security tapes showing the chaos immediately after the 1995 bombing of the Oklahoma City federal building are blank in the minutes before the blast and appear to have been edited, an attorney who obtained the recordings said Sunday.

“The real story is what’s missing,” said Jesse Trentadue, a Salt Lake City attorney who obtained the recordings through the federal Freedom of Information Act as part of an unofficial inquiry he is conducting into the April 19, 1995, bombing that killed 168 people and injured hundreds more. …

… The tapes turned over by the FBI came from security cameras various companies had mounted outside office buildings near the Alfred P. Murrah Federal Building. They are blank at points before 9:02 a.m., when a truck bomb carrying a 4,000 pound fertilizer-and-fuel-oil bomb detonated in front of the building, Trentadue said.

“Four cameras in four different locations going blank at basically the same time on the morning of April 19, 1995. There ain’t no such thing as a coincidence,” Trentadue said. …

… “The interesting thing is they spring back on after 9:02,” he said. “The absence of footage from these crucial time intervals is evidence that there is something there that the FBI doesn’t want anybody to see.
