I think both @mayer and me are thinking the flux vapors and what else you have going on in the air is the issue here. The fumes can be corrosive (Acetic acid in the flux) so over time it can eat into exposed surfaces damaging them.
 
From what you've stated I can't see RF signals being the issue here. You would need an electromagnetic pulse to damage the transmitters in any radio system (Bluetooth, WiFi, etc...) I've not done any testing on how much of a pulse or what frequencies one would need to kill Bluetooth, so its possible Bluetooth is more sensitive than the others.
