Abstract


Health concerns have been a raised after the enormous increase in the use of mobile phones and related base stations throughout the world. In spite of extensive increase in the studies of biological effects of mobile phone radiations with in last decades, little is known about the effect of long term exposure. In this present report, we summarized a review of the literature on the effects of radio-frequency radiation exposure on the permeability of blood-brain barrier. Gazi University Biophysics group have earlier shown that the electromagnetic radiation emitted by mobile phones – also called radio-frequency radiation - alters the permeability of the blood–brain barrier, GSM like modulated fields were found to be more effective than continuous-wave fields. This paper will review some evidence that demonstrates the existence of non-thermal effects and the exposure complexities that must be considered and understood to provide appropriate, more thorough evaluation and guidance for future studies and for assessment of potential health consequences
