flatulent said:This is one of the reasons that all new sets come with earphones so that the antenna can be distant from the body. This helps drivers keep their attention on the road conditions as well.
flatulent said:All that the research can tell is the body heating. There is no research on what the heating causes or even if it is a benefit.
flatulent said:It is possible that this is one of nature's ways of improving society. People who talk a lot on the phone are damaged and those who don't are not.
flatulent said:You may have heard of the old adage "diarrhea of the mouth means constipation of the brain."
flatulent said:The cancer bit I do not believe. Evidently, government agencies do not as well or they would pass laws requiring phones to be used with earphones.
flatulent said:As far as antennas on buildings, they have directional beams and there is the inverse square law. You get more radiation from the sun and that is known to cause skin cancer.
flatulent said:I have three data points on high RF power.
1. One of my elderly friends spent the first 18 years of his life living very near the antenna farm (and taking walks amongst the towers) of his countries foreign short wave broadcast service which used numerous 100 kW transmitters operating all around the clock. He has excellent health.
2. When I served in the military many years ago I worked at a microwave relay site that had several 10 kW and several 1 kW transmitters feeding large ground mounted reflectors. (These were tropo scater links.) All of us lived in wooden buildings about 75 m away from the antennas and in the beam of one of the links. None of us got ill and to this day I have superb health for my age and better than any of my past family when they were my age.
flatulent said:3. The microwave oven safety standard of 10 mW/cm^2 is higher than the side lobe radiation from building top cell site antennas. Microwave ovens have been in common use for over 20 years world wide and there has been no evidence that they ruin people's health.

you really have to look out for is if you feel discomfort (Heating) when in
a RF field you should not stay. Using a head set is good.
With the head set you should tie a knot in the wire leading to
you head, this is like a RF choke, becase the line can be an antenna.
Cheers
mrm said:I'll tell you a story....
Once graduated in Microwave I start joining with a radar firm....
Testing magnetrons I heard a sound like a gentle knoching on my ears repeating about two-four times a second....The strangest thing was that someone could hear that sound and someone not...To tell the truth that sound was produced by thermal stress on brain tissues induced by EM radiation and the strangest thing is that some people had worked in that firm and heard that sount for fifty years and nobody told them wath it was!
This is to tell you that the scientist don't know the effects of some exposure rates and in this situation nobody is kept informed.....
Have a nice day! MRM
flatulent said:RF is strange. My mother could receive morse code with her dental fillings.
The hearing effect could have been from the magnetic radiation from the pulse forming network used to pulse the magnetrons. Hearing is an electrical effect via the nerves. Nerves transmit signals by pulses and not continuous analog signals. Modern RADAR systems enclose the pulse forming network in a box of solid iron with walls at least one cm thick.
How was the magnetron testing done?
When you heard the tappng sound, was the other real acoustic sounds from the area around you reduced?
flatulent said:1. The 10 kW microwave links were operating near 1700 MHz.
flatulent said:2. The father of my elderly friend worked at the transmitting site. their house was inside the antenna farm property and my friend walked up close enough to the antennas that he could notice that the grass grew better near the ground system.
flatulent said:High power RF has been around for 100 years now. In the early days 100 kW was the standard transmitter power level. In comparison, it took much less time for workers with atomic material to get ill frequently enough to deduce that radium and other materials were a health problem.
