Phones use 0.85, 0.9, 1.8, 1.9 GHz spectrums while BT uses 2.4GHz. Higher the frequency, lower is the operating range. Thats why bt's range is just 10m, while phones can transmit to towers miles away.

And power/strength does not depend on the frequency of the wave, but on amplitude

I was actually curious about @Tetsugaku-san's comment, because if it was meant to be a sarcastic joke then he actually has a point.
Bluetooth uses a much higher frequency radio waves (electromagnetic waves) although lesser power (lesser amplitude) but at 2.4GHz IMO, longer exposure to this is worse considering that this is practically the frequency at which most microwave ovens operate. Just a thought, still needs to be proven.

Short exposure to mobile phone radiation - two hours - has been reported in 2003 to destroy cells in parts of the brain important for memory, movement and learning, and could possibly conceivably premature onset of illnesses such as Alzheimers - although we have no evidence of a similar effect in humans. Lund University Hospital Professor Leif Salford says mobile radiation allows harmful proteins and toxins through the brain barrier in rats. He also has found significant degree of damage to brain neurons in adolescent rats.
He said: "If this effect was to transfer to young mobile users, the effects could be terrifying. We can see reduced brain reserve capacity, meaning those who might normally have got Alzheimer's or dementia in old age could get it much earlier." He used rats aged 12-26 weeks because their brain cells were still developing in a similar way to teenagers and younger children. They were exposed for just 120 minutes to radiation equivalent to typical intensive mobile phone use. Sections of rat brains were examined 50 days after exposure. Animals exposed to medium and high level radiation had many dead neurons in their brains - totally different from rats which were not exposed to radiation. (published Feb 2003).

@BlueQuill
I dont think anyone can afford to use theire mobile for such long periods any way...
But you raise a valid point....
Solution to the problem....
Get your mouse to use the mobile for you instead....
Actually why worry, most people I know are brainless....

Just a thought...with the new firmware everyone just installed on their k750 we get increased reception/bars, does this mean the SAR quoted by SE in the booklet will have changed?
