What's worse for you in terms of radiation? Using a cell phone directly or using a headset?

As for Bluetooth, it seems that there is no significant amount of radiation emitted from Bluetooth devices at ALL, phone or not:
"First, though there has been a great deal of research, the evidence pointing to any health hazard from radiation in the 800 MHz to 2 GHz range at the power levels used by mobile phones is, at worst, equivocal. This suggests that if there is any risk at all, it is very small. Second, I have not seen any studies suggesting any risk from Bluetooth. This is not surprising. While a phone needs to transmit with enough power to reach a base station antenna that may be a couple of miles away, Bluetooth has a nominal range of 30 feet." -- http://www.businessweek.com/technology/content/aug2006/tc20060829_289239.htm
