si ça peut vous rassurer voici ce que j'ai trouvé ici :

"There has been much discussion over the safety issues relating to electro-magnetic radiation from mobile phones, so it is worth commenting on these concerns in relation to wireless LANs which do emit electro-magnetic radiation. There are three points which show that wireless LANs are safe.
* Firstly, wireless LANs operate at a power of 35 mWatts, compared to 600 mWatts for mobile phones, or about one twentieth of the energy emitted by mobile phones.
* Secondly, they are not held against the head as mobile phones are, and the amount of energy is inversely proportional to the square of the distance, so that the amount of energy reaching the head will be less again.
* Thirdly, wireless LANs transmit in bursts, and only when they have data to transmit so that is a user wants to transmit 100 M B of data per day then the transmission time will be about 10 minutes.
Together they indicate that any dangers which there may be are trivial in comparison to mobile phones, and even there it is strongly disputed that there really is a danger."
Ou l'on se demande qd même s'il faut continuer à utiliser son téléphone mobile ...
