Unless that "ray" doesn't have enough energy to dislodge electrons and disrupt the molecular bonds. It doesn't matter how many "rays" hit, or how close they are when generated:
if they are not energetic enough, they will do nothing.
The kind of radiation we're talking about is electromagnetic (EM) radiation, or in other words, light. The sort of radio waves used in WiFi and cellphones are far, far, FAR below the energy levels of any visible light. Just as standing under a red-colored incandescent bulb for a thousand years will not cause you to develop cancer, neither will being bathed in hundreds of low-energy radio waves.
You only need to worry about energetic EM rays damaging your tissue when you get up around the ultraviolet frequencies.

I'm trying to explain this to you: there is a threshold that must be crossed before EM radiation is dangerous, and wireless transmissions are NOT that energetic. It's not quantity of "rays," it's not how close they are, it's how energetic they are (think of wavelength). This is the physics, this is how it works. The EM radiation used in wireless simply is not powerful enough, no matter how near or how ubiquitous. The "rays" do not have enough energy to do damage. I don't care about your car analogies because you do not know what you're talking about.
[citation][nom]ProDigit80[/nom]And yes there is data about all this. That's why there are even insurances you can take on if you'd ever die from ear-brain cancer caused by cellphone radiation (which most cancer near to the ear should be).[/citation]
Are you telling me that the fact that people take out insurance on something means it's actually dangerous? It can't possibly be that insurance companies are simply feeding off the public ignorance to rake in the dough?
