Abstract

If I ask you what is the thing that you always have with you? You will probably answer: "my watch", "my purse" or "my diary"…but I am sure a lot of you will answer "my mobile phone"!! and it is normal, in fact, if you think well, this little device can replace all the things quoted before: you can use it as a diary, as a watch, you can play with it when you are in public transports, you can take photographs, you will probably in few years be able to pay with it and we don't have to forget it, you can use it to call someone!! In short, everything is done on it so that you couldn't live without your mobile phone. It is a fact, that nowadays, we need it, and it is the case of 40 million users (against 35 million for classic phones that can give you an idea of the importance taken by this phenomenon in our society)So it is a very common and useful object but what about our health? We have all heard about the bad effect that could be entailed by “our most faithful companion”, so what can we say today about that?

[...] However, it is a recent technology and it will need time to conclude whether these microwaves are harmless or not more especially as sensitivity of one individual to another are certainly very variable. So I will only give you some results. What is sure, it is that these waves entail a tiny but real heating of tissue close to the device and thus of the brain, and this more, especially if the bone is thin and the head small. A study has just revealed that during the emission (the communication), your brain sees its temperature climbing up by 2 to 3 degrees. [...]

[...] The use of mobile phones can be more harmful for people who wear glasses, which is why it is preferable to remove them during the use of a GSM. According to the morphology of the face, the metal side-pieces of the glasses can have a length which can coincide with the wavelength of the relay or mobile and in this case entails the consequences as seen before. At least, it is forbidden to phone while driving because it is proved that risks of accident are multiplied by 5 and that corresponds to an alcohol level in the blood of 0.5 Microwaves can also cause little sparks and are thus to be proscribed in places susceptible to fire (as petrol station, petrochemical factories, etc . [...]

[...] Furthermore we can specify that as the height of the mobile phone is less important whether it is put on the belt or in the pocket, its power of emission will be increased to compensate for its loss of reception. That is why it is recommended to take the mobile away from the body when a free hand kit is used. The hands-free kit has to be of good make. You must watch carefully that the hands-free kit's cord is not parallel and against the antenna or the radiant face of your GSM, because residual microwaves could then be superimposed together and go up along the hands- free kit's cord to the ear. [...]

[...] Concerning the power of these different devices: a mobile phone working in 900 MHz will have a power of 2 Watts whereas those functioning in 1800 MHz have only 1 Watt, a "hands free" phone used in cars will have a power of 8 Watts, antennas for cellular phones a few tens of Watts, television antennas will make several hundred Watts, a microwave oven will have a power varying between 500 and 1000 Watts but for this kind of oven, different ways are used to prevent the waves from going out, like an armored door and a special joint which have the characteristic to stop the waves. [...]

[...] Part II Now we will see that this question is often discussed in fact the fast development of the use of mobile phones and the huge number of relay stations constructed has entailed the fear that the technology of the cellular phones can have harmful effects on the health, while causing in particular migraines, loss of memory, tiredness, depression, cerebral tumors, cancers and even Alzheimer. There are two ways to know if cellular phones entail risks. First of all, we would have to measure the impact in laboratory of microwaves on our health. [...]
