The fact is that levels of radiation are easily measured and areas high intensity are widely known so it would not be hard to correlate disease with exposure to microwave radiation if it were in fact a problem.

And then IF it ever were to become known as a problem do we worry about cell sites with peak power levels of around 900 watts and average of about 30 watts, or do we worry about UHF television stations with power levels of megawatts and radar stations with peak power levels sometimes in the gigawatts?

My own personal belief is that using broad band spread spectrum signalling techniques such as that used in modern cell phone and internet access schemes at relatively low power levels is much more efficient than high power single channel per carrier transmission schemes used by radio and television and so in terms of reducing the total exposure to radiation, and especially radiation that is intense enough to have thermal and real health effects, the proliferation of cell and internet access towers is a good thing.

It’s also good from an energy consumption standpoint and as a society I think the dangers we face from continuing to dump large quantities of CO2 into the air are far greater than those we face from microwave radiation.

A note about that too, Google publicly stated the reason they did so was because peoples FTP servers weren’t working and they end up taking the blame when FTP publishing failed. Well, I’m here to tell you, MY FTP server worked just fine and their FTP publishing STILL frequently timed out even though I could FTP to my server fine WHILE their publishing was failing. They had a problem, didn’t want to admit to it, didn’t want to deal with it, so they just killed it. Personally, I think that sucks but such is life. This is better anyway, now they have zero control over the content.

Now there are some exceptions, if you have metal in your head, and it’s got joints that are a bit oxidized, they can play diodes, and if the signal is modulated, the modulation components can be recovered by the diode effect of those oxidized joints and they might fall within the range that your nervous system can respond to. At really strong signal intensities, there might be enough non-linearity in tissue to do that, but that’s at power levels way above what you’re going to get for a cell or internet access tower and probably to power levels where there are thermal effects as well.

Without knowing the power levels, frequencies, type of service, etc, I can’t be real specific but as long as that 65 feet is substantially above the house and you’re not in the plain of the antenna and very close to it, you’ll probably be okay. This is because the antennas are directional in the vertical plane and radiate their power mostly out horizontally and not a lot upwards to the sky or down to the ground.

Assuming the transmitter is not over a kilowatt and you’re at least 30 feet from the antenna, I think you’re safe. If it’s higher power, or you’re closer, then I’d be concerned. There isn’t a lot of evidence for effects at microwave frequencies at power levels below the point where it causes thermal effects that is solid.

I’ve seen studies that look at cell phones, which today are generally 100mw or less, and show evidence of cancer for people who were using them 20 years ago, but 20 years ago, they were five watt not 100mw and there were substantial thermal effects (I can speak from personal experience, I had one of those 5-watters and it would heat up the whole side of your head).

There are people who claim to be extremely sensitive and get headaches and dizziness with exposure to low levels of EMF but I’ve yet to see a single study that takes those individuals and does a double blind study to see if in fact there is ANY relationship between electromagnetic energy (when they aren’t told it’s present) and their symptoms. People imagine all sorts of things.

People make the argument that the human nervous system uses very low potentials and thus could be disrupted by such signals but human beings nerves operate at frequencies of from a few hertz to a few tens of hertz, not gigahertz. Low frequency electromagnetic radiation is problematic at low levels but no evidence that is true of microwaves.

I hope you are still operating your blog as you are the first source of genuine trustworthy information I found to answer some of my questions but I still have some – about Wireless internet towers. We live in rural Canada and have a wireless internet connection facilitated by a small radio positioned on the roof of the house.This radio transmits and receives the Internet signals to and from towers. The towers are up to 65 feet tall and some are mounted on people’s properties (with their permission of course.) Our internet signal has weakened substantially for the past few months for some reason (after nearly two years of high speed) and the only solution ISP arrived to is the installation of one of those towers on our property. We agreed to it. There going to be 65ft tower positioned very close to the house. Can you give an educated info on the health effects that might give us?
With respect,
Olivia
