electro magnetic waves from cell phone towers are dangoures to humans.?

only if you are constantly exposed directly to the towers for very long periods of time. Other than that they arent that dangerous.

mobile phones use the spectrum below the visible wave length  (  and below IR  ) . those frequencies have low energy typically (though MW is used for cooking...) and are not considered of the ionizing radiation type, which is on the other side of the spectrum ( above UV ). For example: X rays, Gamma rays, etc'...which are definitely dangerous. Nonetheless I'd use a cautious approach and common logic when using any radiating device which has only been around for a few years . if there are negative effects we shall see them years from now on the "heavy users" of cell phones...\nanother issue is that those tumors i guess you're referring to occur because of DNA braking up during transcription by exposure to ionizing radiations ( which has a short enough wave-length ) , that could most definitely NOT occur with your cell phone!\n\nso my answer is - NOT LIKELY.

I really dont think so, i mean if you are talking about em waves given off by electrical equipment of this kind then no.  The only concern with such equipment is that all the connections are properly in place and there is no lose wiring sticking out of it so that it is earthed properly and completely safe.

Overhead power-lines have a high voltage AC current flowing through them, so create a radiating magnetic field for some distance all around the wires.  When this radiated (moving, because the electricity in the cables is changing direction 60 times a second) passes through the aerial on your radio, it is likely to be at some of the same wavelengths/frequencies as something you are trying to receive deliberatly, so you get "the buzz".\n\nCheck this website out for more:

Mine does that. I'll tell you why, too. Whenever you are about to receive a phone call or text message, the radio waves from the antenna become bent and distorted because of the magnets in the speakers. Therefore you have a three-burst buzz that sounds from the speakers.

If you have a device that is sensitive to the frequencies used by cellular phones, then, yes, you can detect them with some degree of accuracy, as long as the phone is on.\n\nTry a device like http://www.globalgadgetuk.com/detector.htm, or do a search for cell phone detector (I'm not sure how legal these are in the US). They'll also give you some cell phone jammers, although jammers are illegal in the USA

Sorry, you're going to have to be a bit more specific than that. Electromagnetics is a rather broad subject.\n\n~X~

Wireless electricity...Sounds kind of complicated.  If they wanted to do it, they could do it from satellites or something.  But it would have the same stipulations as WiFi, there would be areas that transfer the waves, and then there would be areas that don't, because they are out of limit.  Also, if you ever played SimCity, the Electric Satellites have a small tendency to miss, usually during the dry season in a wooded area...not a pretty site...

(m)\n\nThe electric and magnetic field associated with most electrical appliances and power lines are at the extremely low frequency end of the electric and magnetic spectrum. They have a frequency of 60 cycles per second, or 60 hertz (60 Hz), because the alternating electrical current that creates them changes direction 60 times per second. Radio and television broadcast waves are farther up the electric and magnetic spectrum. Visible light, which is at an even higher frequency yet, is the most familiar form of electric and magnetic energy.

Its said that cell phones.. When you're blabbing away on your cell phone, did you know that your voice is transmitted from the antenna as radio frequency radiation? In fact, your voice puts out about half as much radiation as a microwave. Too bad we can't cook up a meal simply by talking to it on our cell phone.\n\nIt shouldn't come as a surprise that with that much radiation flowing from your phone, there's a good chance it's going to soak into your brain and cause some kind of damage. Cell phone users are at risk for getting rare brain tumors. In fact, studies have found that the rare tumors happen on the same side of the head that people usually use to talk on their cell phones.\n\nMillions of people use their cell phone on a daily basis - America alone has about 123 million cell phone users. Are you one of them? If so, you are putting a high-powered transmitter against your head - about an inch away from your brain. So don't sound so shocked to hear that talking on your cell phone might cause some serious damage.

From the point of view of Physics, an electromagnetic (EM) wave is a self propagating wave in space with electric and magnetic components. It carries energy and momentum which may be imparted when it interacts with matter. EM wave can be predicted by Maxwell's equations. \n\nFurther informations: http://en.wikipedia.org/wiki/Electromagnetic_wave

High frequency radio waves. Around 1700 Mhz.

Electromagnetic radiation travels (propagates) by means of oscillating electromagnetic fields that pass through the air and the vacuum of space equally well, and does not require a medium of transport (such as the aether). When radio waves pass an electrical conductor, the oscillating electric or magnetic field (depending on the shape of the conductor) induces an alternating current and voltage in the conductor. This can be transformed into audio or other signals that carry information. The word 'radio' is used to describe this phenomenon, and television, radio, radar, and cell phone transmissions are all classed as radio frequency emissions.

It is not a problem for both the computer and the cell as cell phone is a wireless communication, cell recieves the content in the form of a wave so during the wave transfer there will be lot of disturbances and the computer will easy identify the wave transfer. so better keep ur cell away from the system.

I've heard it could cause health problems because of the electromagnetic energy. Doctors are also concerned because so many kids are using cell phones now. I only use mine when I have to. I really do hate them.
