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.

The wireless signals in your home, you'll be glad to hear, are a form of non-ionising radiation-Radio Waves. The Radio Waves emanating from your Wireless router and Wireless adaptor are about 15 to 20 times lower than that from a mobile phone. However, the SAR values for phones were derived from short bursts to the head. Wireless signals are constant, so it is difficult to compare the two.
