Answer: No. Mobile phones do not give off sub-atomic (ionizing)  radiation.    Answer: Yes. Mobile phones emit microwave (millimeter to  centimeter range) electro-mag â¦ netic radiation, mostly at frequencies  from 800 to 1800 MHz (1.8 GHz).This is below infrared.nswer: No. Mobile phones do not give off sub-atomic (ionizing)  radiation.

Bluetooth Technology uses the same microwave radiation to transmit data as cell phones do to receive calls. The only difference is the range. A cell phone antenna picks up signals from cell phone towers and satellites, while a Bluetooth headset/technologies is receiving radiations from a few feet away.
