Studies on Thermal and Non Thermal Effects of Cell Phone Radiation on Human Tissues

Abstract

In the present work, a theoretical model has been proposed for the study of penetration newlinedepth, attenuation coefficient and specific absorption rate (SAR) with varying distance newlinebetween the source of radiation and exposed human tissues. In addition, corresponding newlinetemperature increases inside these various human tissues are also calculated. The newlinenumerical analysis of thermal effect inside human head tissue, eye tissues and skin tissues newlinewas done for two types of mobile phone GSM radiations i.e. 900 MHz and 1800 MHz. newlineThe non-thermal effects of cell phone radiation on the human heart using newlineelectrocardiogram, blood pressure level and sugar level have been examined before and newlineafter cell phone radiation exposure. For electrocardiogram analysis the parameters like newlineHeart Rate, Rhythm, Mechanism, Axis, P wave, PR Interval, QRS complex, ST segment, newlineT wave and QT Interval has been examined. The study of Electromagnetic pollution newlinecaused by cell phone towers has been done by measuring the environmental power newlinedensity near schools, hospitals and old age home. Because young children due to their newlinedeveloping stage, patients and elderly people because of their weak immune system are newlinemost susceptible victim of these radiations. The study has also been done to provide a newlinesolution for electromagnetic interference in terms of microwave radiation absorber newlinematerials. For this Al-Cr doping has been employed in Y and Z type hexaferrites and the newlineeffect of doping on structural, magnetic and radiation loss properties has been examined newlineusing XRD, FTIR, VSM and VNA. The Y and- Z type nano-hexaferrite samples i.e. newline2 2 / 2 / 2 12 22 Ba Mg Al Cr Fe O x x and#61485;x ( x = 0.0, 0.5 and 1.0) and 3 2 / 2 / 2 24 41 Ba Cu Al Cr Fe O x x and#61485;x newline(X=0.0, 0.5, 1.0) have been synthesized using sol-gel auto combustion method. newline
