Is this for real or a spoof.

I believe cell phones to be safe, and I would posit that the reason our brains aren't 'hard boiled' is that our function of homeostasis takes care of the excess heat before it does any damage. The egg can't do this.

I don't think the power source of a cell phone could handle it anyway.

[tp6626]

No thats what I was thinking. I bet a phone doesn't have more than a few watt hours in its battery, and I doubt this is enough energy to boil an egg.

I'd have to get my thermodynamics books out to work it out. But I can't be bothered right now.

If you cause the battery to have a thermal melt down it may generate enough heat to boil an egg. As for the signals they send out? never.

I've seen videos of cell phones being used to pop popcorn, so I guess it's possible to hard boil an egg in the same way.

However, I don't think this is proof that cell phones are dangerous for humans. First of all, cell phones emit radio waves, which to my knowledge can't ionize molecules and therefore can't cause mutations, i.e. cancer. All they can do is heat things up. However, the human head is larger than either an egg or a popcorn kernel, so it would take significantly more energy to heat up someone's head to dangerous levels than it would for an egg or a popcorn kernel. Not to mention that in the videos I saw, it took at least three cell phones to pop four or five measly little kernels, which is at least two more cell phones than anyone would be holding to his or her head at any given time.

I think the concern is about low-dose, long-term exposure. I don't think it is completely clear that even non-ionizing radiation is "safe" under conditions of frequent exposure. Unfortunately, this question is hard to investigate.

[Sean O]

Yeah, I figured that was the case, but if all non-ionizing radiation does is cause things to heat up, then wouldn't any difference made by low-dose exposure go away fairly quickly? Not to mention that cell phones aren't the only source of this kind of radiation that we encounter on a daily basis. Sure, in the case of cell phones the source is right beside your head, but if non-ionizing radiation was really a health hazard, wouldn't the invention of the radio, television, power lines, microwaves and so forth have had a noticeable effect by now?

Either way, I've in a few articles that any evidence that suggests repeated exposure to cell phones is dangerous is still controversial. To me, it seems unlikely that it would be particularly dangerous unless we discover some new property of non-ionizing radiation, or perhaps of cellular material.
