That contradicts a bit with the Finnish study which found that people who used the phones for more than 10 years were 40 per cent more likely to get a brain tumor on the same side as they held the handset.

Since nothing is sure, It is better to use them as little as possible before we know for sure.

Mobile phones don't cause cancer unless you eat it or switch them on start using them.

As of the radio-frequency electromagnetic fields emitted by mobile phones, it not only can cause cancer but these waves penetrates through the eyes, warm them up and increase inner pressure that might lead to glaucoma and blindness.

It doesn't matter whether you have a mobile or reduce using time, as everybody uses them night and day everywhere even both of your neighbors in the train, so you have no chance to escape from your daily dose.

Usage of Mobiles phones increases to very high level from 10Y to now. Real test can be made after 10Y. Now they study what is happen, when you use your phone in the past :).

What about people (men) that put their cell phones in thier pockets? Don't they still give out frequencies even while not in use(talking)?

Munya, your comments scare so much! Warm up our eyes from the insides and increase pressure leading to glaucoma and blindness?? I hope you are very wrong about this and as many others posters here would ask, supply some link, web pages etc..to this kind of information please.

Munya, maybe you should read up on the inverse square law.

Sorry I don't have links or ref., I started studying this issue many years ago first in connection with home-appliance micro wave ovens, isolation etc. I even had I small very simple antique testing/checking device that started glowing in electromagnetic field. I got it from one of my friends who had been working in a therapy institute, as many years ago in hospitals both ultrasonic and radio-frequency electromagnetic waves were used to cure rheumatism, pain in joints etc. as they trigger chemical changes in the body cells and warm them up especially the liquid in the cells. These equipment and kinda cures may not be in use any more. maybe they are in some countries.

I know this as I have many friends , doctors, therapists in many countries and many times we discussed this topic even in details of wave length, frequency and field intensity. It was many years ago, since then I didn't pay attention to this topic, sorry.

John BeckerOct. 25, 2011 - 01:52AM JST

What exactly, sorry I don't know what you mean.

Munya: the inverse square law states that the intensity of electromagnetic radiation decreases as an inverse square of the distance. If you get 1 "unit" of radiation at 1 meter, you get 1/4 "unit" of radiation at 2 meters, 1/9 "unit" at 3 meters, etc. So compared to someone holding a cell phone to his ear, a person standing a meter away receives almost no radiation.

This is completely wrong.

@John Becker

I've got it now. Thanks for the explanation. Yes, indeed, I remember I saw a few of those old machines for therapy , which worked with electromagnetic radiation, they had around 20 cm diameter disks on flexible arms and they were put close up on the patients body just a few centimeters.

Well, I don't know the field intensity of the mobiles or how they can be measured in a simple way at home or if there is a possibility for any protective isolation. Anyway, when sitting on the train on the left on right their mobil phones are app.30 cm from my head. Frankly I don't like it. Once again thanks for the explanation, at least a good news.

@John Becker

P.s.

Also, I had somewhere that antique indicator that a friend of mine gave me, when she said those therapy machines were taken out of use, that was glowing in blue light when the intensity of the magnetic radiation reached a certain level. I have no idea what it could be might be some specific bulb inside, it was in a black bakelite case I only could see the small glass glowing tip.The whole thing was small.

Munya:

Actually it is true that eyes are sensitive to heat, because there is not much blood flow, which could lead to cooling. In this way, looking into a 500 W open Microwave will not be good for the health of a person, therefore there is a security switch.

On the other hand, the output power of a mobile pone is limited to a maximum of 2 W. The average power is much lower, so that it is less demanding from the battery and hence the phone can be used for a longer time before recharging. A mobile phone battery might have in the order of 3 to 4 V and a current capacity in the order of 1000 mAh (milli-Ampere-hours), in other words between 3 to 4 Wh (Watt hours). So if a phone allows a talk time of 8 hours, the average power is less than 0.5 Watt. Compare this to the 100 W of heat, a normal human body is generating even at rest to reach a body temperature between 36 and 37 deg. Probably your face will heat up much more from the content of the discussion on the phone than from the radiated power.

These are some simple numbers, which are easy to confirm, which will give you some idea.

Things are different when talking about mobile phone base stations. These have a power output in the order of several 10 Watt and therefore they are put in places (on rooftops), where it is possible to guarantee some distance (remember the one over square law by John Becker).

A little bit more dangerous is military radar, where the pulse output can be up to 1 MegaWatt. You definitely don't want to watch into such parabola antenna, when it is operating.

@electric2004

Thanks a lot for taking your time helping me with a long post. I think I can see clearer now as your post lit the lite in my brain, yes the base point.

As I said in my post we discussed it with my doc friends and there were electric engineers among us too, they were from different countries with different technological and medical background, and now I clearly remember we discussed the therapy equipments and the early cordless phones with base point where the user had to get closer to the base point to be able to make a call.

I was very young at that time and the mobiles that we are using now were not yet in circulation then and my recollection was incorrect as all what remembered were the micro wave isolation, the therapy equipments and some early technology cordless.

Now, it was many years ago when we discussed it, so, I think you are on spot with the mobile phone power output. I gonna go back and look at the bottom of this issue again from the angle of the biological medical side.

Thanks anyway for your help also John Becker, at least my first post didn't remain unrevised and it could be corrected now. Thank you guys.

Electromagnetic radiation has an effect on the human body?

Of course it does.......

Might not be easy to determine how it affects us. I think there should be much more to discuss beyond field intensity, such as wave length, frequency, speed , isolation, effect, impact etc. Some wavelength are harmless for human body even in high intensity, some other wavelengths are killer even at week intensity. Time, extent of exposure etc.

Just two sample; although the output power is little , yet mobiles are banned in hospitals as they can cause problems for patients with pacemakers, so its week field intensity is still enough for messing other equipments, or just if you put your mobile in a well isolated micro oven (don't switch it on just place in it -:D) and you call the number it will ring even in a concrete walled kitchen. That's about effect, impact and isolation. There are many more facts to consider.
