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.

There still aren't any good explanations for how mobile phones could cause cancer. The radiofrequency electromagnetic radiation they transmit and receive is very weak. This radiation does not have enough energy to damage DNA, and cannot directly cause cancer.In 2012 an independent report concluded that there is no convincing evidence that being exposed to radiofrequency fields, including those from mobile phones, within the guidelines could affect somebody's health.here has been some media speculation that Wireless internet (Wi-Fi) and smart meters, which can be used to record energy use in your home and transmit it back to your energy provider, could cause cancer. Smart meters and Wi-Fi both use radio waves to send information.
