Bluetooth, is it safe?

[qapmoc]

As there are many opinions about using mobile phones and the safety aspects of having a radio transceiver close to your head for long term use, then how do things such as bluetooth headsets for mobile phones and MP3 players etc... stand in this dispute. surely they are even worse because they are really close to your brain and when in use are transcieving continously.

probably not that dangerous.

for one, their frequency range isnt as dangerous as the microwaves that your mobile phone itself uses.

secodly, its nothing like as powerful. your mobile has to communicate with the phone mast up to 1/4 mile away or so; your bluetooth only works for about 10 metres...
