Story time everyone.
My computer networks professor last year was originally from China, and heard about this from one of his professors there.
There was a town in China that had (at the time) recently had a cell-phone tower placed in their near vicinity. The company that put it up received a large number of complaints from the people in the town expressing a wide variety of symptoms that began after the tower was put up. Nausea, inability to sleep, and some people even claimed that when they looked at the tower they could feel the electromagnetic radiation burning their eyes.
As you can guess, their symptoms were all in their heads. In fact, against all logic, putting a cell phone tower near your town actually reduces the amount of electromagnetic radiation you're subjected to. Why exactly is that? Well...
The amount of electromagnetic radiation you get from a cellphone tower is inversely proportional to the distance you are away from the tower... cubed. The actual formula follows something along these lines: P/r^3, where P is the power of the signal, and r is the distance. What this means is that the electromagnetic radiation you get from the tower that's 1000m away from you is one billionth the power of the tower.
On the other hand, you're putting your cellphone right up against your head. Let's say that it's 1/10 of a meter away. You're getting 1000 times the power of your cell phone in electromagnetic radiation. Now obviously, cell phone towers have more power than a cell phone, but it's not 1 trillion times as much power. A 1 minute call on a cell phone will give you as much radiation as 19 years 1km away from a cell phone tower.
Now why are you better off closer to a cell phone tower? Because cell phones try to use as little power as needed to keep a signal. The closer a cell phone tower is to you, the less radiation you're getting from your cell phone, which is by far the larger source of electromagnetic radiation.
The company sent out representatives to go door to door to the townsfolk and explain this to them. Anyone want to guess how that went?
