Effect of Mobile Phone Radiation on EEG

Abstract

The electroencephalogram (EEG) is a record of the oscillations of brain electric potentials. The EEG provides a convenient window on the mind, revealing synaptic action that strongly co-relate with brain state. Fractal dimension, the measure of signal complexity can be used to characterize the physiological conditions of the brain. As the EEG signal is non linear, non stationary and noisy, non linear methods will be suitable for the analysis. In this paper Higuichi's fractal dimension analysis is applied to find the fractal dimension of EEG. EEGs of 10 volunteers were recorded at rest and on exposure to radiofrequency (RF) emissions from mobile phones having different SAR values. Mobile phones were positioned first at the auricle and then next to Cz position. Fractal dimensions for all conditions are calculated and analyzed using F-test, In most of the cases, null hypothesis is rejected with 95% confidence. This statistical result shows that there are some changes in the FD while using mobile phone, which demonstrate transformation in the activities of brain due to radiation.

An Experimental Investigation of the Impact of Electromagnetic Radiations Emitted from Mobile Phone on General Health, pH, Flow Rate and Electrolytes Concentrations of Saliva in Female Adults

“…For testing unstimulated pH saliva, the participants were directed to expectorate the saliva into a sterile collection cup for a duration of 5msinutes. Then, pH test strip was placed into the saliva sample for 10s, and then color change of the stripe was checked and compared with the testing chart available with the package of universal indicator paper (pH [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Finally, the collected saliva was experimented for saliva electrolytes (sodium and potassium) by flame photometer (BWB XP).…”

“…Electromagnetic radiation can be classified into two types: ionizing radiation and non-ionizing radiation, based on it is capable of ionizing or non-ionizing atoms, molecular and breaking chemical bonds [1,2]. Mobile phones send and receive information use electromagnetic, non-ionizing radiation in the microwave range (radio-frequency [RF] waves and microwaves) [2,3].…”

“…It includes both studies of cell cultures and tissues (in vitro) and of laboratory animals (in vivo), as well as of human. Recent investigations conducted reveals that long-term usage of mobile phones can damage health [1]. It is associated with headache and dizziness [11], decrease in sperm count and mobility [12], disruption of sleep and circadian rhythm [13], memory loss [14], decreased immune function, higher blood pressure and reduces DNA repair capacity [15].…”
