Infrared headset nixes radiation Many cell-phone users have taken to using hands-free headsets to avoid the microwave radiation the devices emit, but the electrical wires that connect the headsets to the phones can also act as antennas for microwaves. A headset that connects via infrared light sidesteps the radiation problem. mark for My Articles similar articles
