Also: Cell phones can have screensavers? I thought people just kept 'em closed when they aren't using them.
I see you have evaded the questions put to you and totally ignored my 1 watt energy within a small volume example.
I knew you would do this to protect big business.
Your assertion of education by corporate interests in the form of advertising of their products smacks of ignorance.
You are also ignorant of the fact that brains cannot feel pain.This is why surgeons can operate on a conscious person.
Also radiation impinging on flesh will not always result in sensation.
If you were subjected to gamma radiation or x -rays you don't feel it,but the damage is still done.
You claim you are all knowing yet you are ignorant of the simple fact that cell phones have screen savers and wallpapers too.
Dielectric coupling is an established fact and cannot be ignored just because you say so.
A microwave oven heats because the energy is largely absorbed by water molecules.
Humans are largely made of water hence the dielectric coupling.
Water has a very high dielectric constant of 80.

Stop being an internet tough guy and accusing me of working for corporate interests. It's annoying. The mod already said to address arguments, not
posters. Keep it up and I'll report you.
Sure they heat things. But the effect is insignificant. It's not doing damage, it's heating you. But not by much at all. It's an more or less omni
directional uncollimated radiation source, Furthermore, it's a source of relatively harmless MICROWAVES. For god's sake, for a given level of
exposure, they're some of the least harmful rays out there, second only to radio. They've got next to no energy to 'em. Unless you manage to cook
yourself with 'em, northing's going to happen. And I think it's CLEAR to anyone who's ever used a cell phone that it's not cooking their flesh.
At peak, you're receiving about as much energy to the side of your head as you do from sunlight on a bright day. Also: they tend to be designed so
that you're not taking up too much of the phone's radiation with your head, because radiation going into your head isn't helping your reception.
Any modern phone has a patch antenna facing away from you.
The difference between microwaves and gamma rays and X rays is pretty obvious. X rays and gamma rays are ionizing high energy radiation. They punch
right though you and knock bits out of your DNA (and any other poor molecule that happens to be in the wrong place at the wrong time). Microwaves are
low energy EM that doesn't do much but heat polar molecules through dielectric coupling. Heating isn't the same thing as BLASTING HOLES IN THINGS
YOU NEED TO LIVE. Radiation that penetrates well doesn't make for much of a sensation, since it misses the temperature receptors in the skin.
Microwaves penetrate poorly and result in direct heating. Hence why they're used in that military pain-ray. People can clearly feel them, when the
amounts are high enough. People can feel it when their microwave oven is leaking, and that's on just about the same frequency as cell phones, just
with more power behind it. It should feel about the same as an equivalent quantity of pure IR. 2 watts of that on your face ain't gonna phase you.
Call somebody up and wrap your hands around the antenna. If it's heating you, you'll eventually feel it. Microwaves have poor penetration, so it
should heat up your flesh at the skin, or close under, where your temperature receptors are.
A few degrees of warmth on the side of your head isn't harmful anyway. Unless your propose we assassinate people by sticking those exothermic
therapeutic heat pads to the sides of people's heads. Heat doesn't cause cancer, last I checked, even applied slightly subdermally. You've got
blood to maintain temperature homeostasis, anyway. We humans are water cooled.
I'll admit, I am ignorant of cell phones, as far as newfangled features go. (I've never used mine to browse the web, download music, or use AIM,
etc.) I've owned all of two in my life, both of which are outdated, and were, in fact, pretty much outdated when I got them (frikkin' verizion and
their no SIM chip policy.). I know they have wallpapers, but I've never seen a screensaver on a cell phone. especially not a video one.
I just leave mine on my desk most of the time, since I use various internet chat programs to talk to people, not phones. Oftentimes, mine runs out of
batteries between me using it, just from sitting around on idle with the screen off, waiting for calls. Not because I think it's unsafe, but just
because I have little use for the thing.
