Photon energies of RF electromagnetic waves have not a level to be able to ionize atoms and molecules.

Visible light, infrared light and RF waves which are the low frequency form of electromagnetic radiation are the example of non-ionizing radiation.

As a result of exposing to non-ionizing electromagnetic waves, two kinds of effect can occur in organisms: Thermal effects and non-thermal effects.

Thermal effects are defined as the electromagnetic energy that is absorbed by body, is converted to heat and increase the heat. This heat continues to increase until it is balanced by letting out it with blood stream. Heat increase that can be caused by RF sources like cell phones is normally very low and probably can be neutralized by body’s common mechanisms.

The heat increase that can be created in brain is nearly 0,1⁰C [11].

Illness and disturbances which are claimed to be depended on non-thermal effects but affected from RF waves consist insomnia, inattentiveness and headaches.  But, these risks can be valid for very high experimental doses and time of exposure and these results are not valid for cell phone usage.

Highly energized ionizing electromagnetic waves can cause molecular changes that can damage to the DNA and biologic tissues which are containing genetic materials.

This effect can be come through by interacting with highly energized photons such as x-rays and gamma rays.

It is known that the ionizing radiation causes to mutation and cancer by effecting genetic material of cell (DNA) in addition to RF waves that have proven similar effects.

In recent years, the matter of that if cell phones increase especially brain tumors has came up, but the researches that was done until now, didn’t show any definite evidences about that the cell phone usage is causing cancer. Finally, the detailed researches that are performed in U.S.A and Denmark are clearly showed that the cell phone usage does not increase the brain tumor risk [12]-[14]. On the other hand, researches which are performed until now, are not enough to say that there is no any relation between cell phone technology and cancer. Therefore, foremost World Health Organization and other organizations started much more detailed researches about this matter. It is expected to get the results of these researches in the coming years.
