You are right, BT is only intended to transmit with enough power to communicate a small amount of data over a few feet. There is much much less radiation from a BT headset than a cell phone.
BT headsets have SAR ratings of 0.001 and 0.003 W/kg vs phones that are from .2 up to 1.6 W/kg max. Depending on which cell phone you use a BT headset might have a SAR rating a thousand times lower.
BT is even ~10x lower than cordless phones which are 0.01 and 0.05 W/kg SAR
