At home, is it preferable to use a cordless phone rather than a mobile phone? Does the cordless phone emit more radiation when not resting on its support?

The home cordless phone transmits signals to its base in order to route a conversation outwards, thus emitting non-ionizing radiation.  In general, cordless phones have a significantly lower output than that of mobile phones.  Since the distance between the phone and its support is relatively small, there is no need for a high intensity of transmission, and the level of radiation is consequently low.


When the handset is not placed in its base and not in call mode, the emitted radiofrequency radiation is relatively low (compared to during a conversation). There are some models where the transmitters are switched off during the non-call mode, thus not emitting any radiation until a call is initiated.


When the phone is placed in its base, the radiofrequency communication channel is usually disconnected and therefore does not emit any radiofrequency radiation, but there are some devices that do not disconnect the communication channel in this mode.


It may thus be concluded that in general, the level of radiation emitted by cordless phones is lower than that from mobile phones.


It should be noted that the newer cellular networks adapt the emitted radiation to the location of the device and to the technological profile of the network.  Therefore, the mobile phone may adapt the intensity to the lowest possible level of radiation, so that the radiation emitted by the mobile phone may in fact be lower than that of the home cordless phone.
