[citation][nom]aftcomet[/nom]How about health? As much as I love technology, human health comes first. We're still not sure of all the effects of radiation. Are we all going to have cancer in 40 years?[/citation]
We actually are sure of all the effects of radiation (at least, if you're talking about wireless radios, cell towers, etc.). That is, they don't do anything to humans. Those who report that they are adversely effective have, in all cases, been totally unable to reliably reproduce the effect. In fact, there's a $1M prize standing for any human who can detect radio signals. If these people's symptoms were actually a result of what they claim, then one of them would have walked away with the prize years ago.
In truth, these people are simply blaming radio signals for symptoms they can't find any other cause for, and that may even be psychosomatic (all in your head). This is largely a result of the proliferation of wireless devices combined with confirmation bias. They get a headache and look for a cell phone or GPS to blame it on, find it, and use that as confirmation that the cell phone or GPS caused it. It would be just as valid to blame it on wearing clothes, being in contact with Earth's atmosphere or blinking.
The reality is this kind of radiation is safe. The energy level is much too low to damage cells, except potentially at very close ranges (and even that is contested, with studies turning up nothing conclusive). It's also non-ionizing. There have also been powerful radio towers broadcasting for several decades now.
In short, if there were serious health issues, we'd have seen them by now. The jury is still out on whether or not putting a cell phone antenna next to your brain is a good idea, but research is being done.
