Yesterday I had an unnerving, rude awakening about something and I’d like to ask a question about it. I was watching TV and thought of an automated number I needed to call and dialed it on my cellphone. I was very close to the TV. While the cellphone was dialing it I heard quick, definite pulses of static in the set and saw little shivers in the picture and after the phone had accessed the number a continuous crackle of static. It got me thinking…I think there might be something to the idea of too much cellphone energy in a day/week/month doing damage to our brains. Because I could definitely see that the energy was enough to disrupt my TV reception (and it was the cellphone-it stopped when I hung up and started again when dialed another number). And I know that cellphone batteries carry a wollup of a charge. They have to! They have to get to 99.99% of the world, for the customers. It’s just that that kind of jolted me. Not that we can do anything about it of course, but out of idle curiosity just what kind, how many and what intensity of waves are going through our bodies and what do they do?
Now that you mention it, I’ve had a similar experience.
I have the poor man’s audio setup in my car (Discman with that tape adapter thingy), and when my cell phone rings, the music either stops altogether or picks up considerable static.
A little googling on the problem revealed diddly squat, and I know nothing of electronics, so I’ll leave that to someone else.
To address your concern about radiation and our brains, a plethora of studies have been done, with as many results.
I suppose we’ll truly find out a few years from now…
You’re more likely to be affected by the stress of worrying about the effects than you are by the effects themselves. Think about that. 
But seriously, your cellphone has to transmit radio signals far enough to reach the nearest tower, not 99% of the world. The signals from the towers have to be stong enough to cover the area to the next tower. These signals, and many other more powerful ones are being transmitted all over the place all the time. And they’re ALWAYS passing through you. Also, just because something causes a little static on your TV doesn’t mean that it is doing damage to your brain.
Say, your cell phone causes little bits of static on the television, but FOX causes whole screenfuls of crap! You must shield yourself from the television rays! And radio waves, and microwaves, and solar rays, and Sugar Rays, and ultraviolet rays, and… 
The correlation of cellphones messing with tv signals has nothing to do with cellphones messing with our brains. They are two different things. It’s like saying earthquakes mess with our brains. “Well it must, because all the buildings have crumbled, how could it not?”
