Harmfulness of mobile phones

Résumé du document

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?

[...] As the quantity of absorbed energy is low, the heating will also be low. If for example, we take water which has a high dielectric coefficient, the wave will lose a lot of energy while going through it, which will entail a heating and a low penetration. It's interesting to notice that muscles, different organs and the skin contain a lot of water. On the other hand if we take a matter which does not contain water, that means with a low dielectric coefficient, like bones or fat, waves will go through it while losing a minimum of energy, which wants to say that the skull does not protect you from the ultra high frequencies. [...]

[...] However, it is a recent technology and it will need time to conclude or not with the harmlessness of these microwaves, more especially as sensitivity of an individual to another is 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 from 2 to 3 degrees. [...]

[...] ) That last two examples show that the most dangerous thing concerning phones are probably not their waves. CAREFUL: As soon as you begin to perceive headaches, an embarrassment, a heating, when you use a mobile phone, you must stop the communication in the course. If you perceive a pain each time you have a GSM close to your face, you must consult a neurologist imperatively. Conclusion As you can see, we can't know whether our phone is dangerous for our health or not. [...]

[...] You have to wait few seconds, this time allows your mobile phone to regulate and reduce its power. ( The use of a mobile phones can be more harmful for people who wear glasses, that 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 seen before. [...]

[...] Unit used for the high frequencies: ( Specific rate of absorption The specific rate of absorption represents the speed of transfer of the wave's energy in the matter in other terms it is the rate at which the body absorbs emissions from the phone handset. The dielectric constant is the factor that specifies the loss of the energy of the wave in the matter. If it is high, it indicates that there will be an important loss of energy in the matter what will entail a little penetration of the wave and a heating. [...]
