the part that is 2-3mm from your ear is a speaker. the radiation devise is
housed elsewhere in the box. you are attempting to determine the distance of
the mechanical device, which has nothing to do with electric radiation.
I would presume the electronic portion of the blutooth device is much
IIRC, the em wave has a spherical wave front but that is the surface
of a sphere not the volume, so the square law applies. If it did
fall off at a cubic rate there would might be more cause concern
because you the wave energy at the transmitter would be much more intense
to reach the target
Anectdotaly, the fellows who manned the pirate radio stations in England
were known to have their hair fall out.
That was MI5 using some of the left over powder the CIA had made for
Castro.

Also, my own bluetooth headphones are almost always simply
*receiving*. They only transmit when I change a track or am in a call
talking. Sorry, but compared to the very real danger of say, driving
to the grocery store, I can't get too upset about radio waves.

I did hear her on a few show while on her book tour and noted her concern
about the potential harm from cell phones and about the research on this to

Re. bluetooth, is it definitely the case that it gives off much less
radiation than cellphones? Even if so I wonder about the effect of
I have often wondered if those people who wander around yakking on their
cellphones in the middle of stores, traffic, etc. were mindless idiots
before they stuck those things in their heads, or did they become
