Now they will re-focus the study to try and determine if this is good, bad or neutral.
The radiation emitted after just 50 minutes on a mobile phone increases the activity in brain cells, according to a new government-funded study.
The effects of that brain activity are not known, said the researchers, who called for more study.
Phones that were turned off did not create the same brain activity.
The small study, published in the Journal of American Medical Association, is the first to look specifically at how electromagnetic radiation from cell phones affects glucose metabolism, a normal function, in the brain.
"When glucose metabolism goes up, it activates cells. The findings are an indication that exposure to cell phones activate the brain much more easily than we previously thought," said Dr. Nora Volkow, National Institutes of Health neuroscientist and lead study author.

Having seen some of the nitwits yammering on the things while they drive, I have determined that they do, in fact, melt your brains.
I heard something about this on NPR. Apparently, the amount of brain change is smaller than what occurs when you blink.

But what if you blink while using a cell phone? :evil:

I dunno, part of my problem with this kind of study is that it isn't cross-referenced. By that I mean, why not study people who work around high voltage all day? I think the EMF distributed by several thousand volts would be far more significant than a cell phone.
That brings to mind another issue I've been thinking about. Just because we can measure it, doesn't mean it has a noticable effect.
For example, the arsenic level in drinking water used to be 50 parts per billion, with no noticable adverse affect. But then we developed a detector that could go smaller -- as small as 10 parts per billion, which we set our new standards to. But as impressive as a reduction of five times the previous standard sounds, it's pretty much meaningless as far as an effect on our bodies go. And then New Jersey sets their own limit of 5 parts per billion -- a 50% reduction! Guess what? Even more meaningless.

Exactly. I have been following the dog and pony show about the recent solar flares and how they
could affect communications and power grids. Some are trying to make it a sky is falling scenario and others are saying it's not likely. Yes, we can measure the size of the flares, but we really don't know what we are measuring at this time. Maybe at a later date we can say with some certainty that if a flare exceeds a certain size then X will happen. Until then it's just a measurement.

I don't know that it'd be that strong of a field (high voltage lines usually have a very low current), except maybe around a transformer.

You've never worked in an industrial power distribution center. Also find some honey bees around high voltage lines.

They aren't saying it is, but they are going to try to find out.
I was thinking more a lineman. A power distribution center is loaded with transformers. That's not a high voltage thing, any transformer produces a hell of a field (it's actually the whole design of the transformer).

Basic math to begin with. P=IE
Even with relatively low current, 120,000 volts is going to pack a punch.
In a power distribution like I worked in we are talking 13KVA.
Slightly more advanced math: B=m0I/Pir^2
B here is the strength of the magnetic field, m0 is a constant. Voltage isn't part of the equation for the strength of a magnetic field.
Edit: the above equation assumes a non coiled wire. Coil the thing up (like in a transformer) and the field strength goes way way up.

No, but that's a matter of it potentially breaking or me accidentally making physical contact. The magnetic field is like getting worried about catching the flu from a tiger.

Oh! I know! A natural fault could shift causing an earthquake making the power line towers to topple over. Then as all the lines snapped and came crashing down they would snake wildly all over the place wiping out an entire neighborhood in under one minute!
