Do Cellular Phones produce Radiation

Answer 1

Answer: No. Mobile phones do not give off sub-atomic (ionizing) radiation.

Answer: Yes. Mobile phones emit microwave (millimeter to centimeter range) electro-magnetic radiation, mostly at frequencies from 800 to 1800 MHz (1.8 GHz). This is below infrared.

Off Topic: Some independent scientific studies indicate (however, most contradict) that mobile phones may have health effects, including increasing the risk of brain cancer and other cancers and damaging fertility.

Answer 2

Any radio transmitting device gives out radiation - it's the type of electromagnetic radiation we call radio waves.

If you're asking "do mobile phones give out *ionising* radiation", you need to understand that, as wavelength gets shorter (from radio, through infra-red, through visible to ultraviolet and beyond), electromagnetic waves get more energetic.

Eventually (into ultraviolet), they get so energetic that they can strip electrons off from atoms and leave the atoms ionised (charged), hence the term "ionsing radiation", and this is dangerous as it's shown to lead to cancer (think of skin cancer from sun exposure).

Do phones emit ionising radiation?

No.

Do phones cause cancer? By the previous question, no.

Do they cause brain tumours? The folks who say "yes" are still to be convinced that there's no current evidence for this.

Answer 3

Cell phone screens emit visible radiation, also called "light." They must do this, otherwise you would not see them.

Answer 4

Radio Frequency Emissions.

A cell phone is just a complex microwave walkie talkie.
