Introduction: The use of mobile communication systems has dramatically increased over the past decade. Although many studies have been performed to determine the effect of radio frequency (RF) but less attention has been paid to the possible biological impact of exposure to extremely low frequency (ELF) components. The objective of this study is two folds. One is to design the ...
Introduction: The great use of electrical appliances in different life applications is one of the most obvious concerns because of its possible health drawbacks. These investigation reports results of electromagnetic field effect emitted from mobile phones on some biophysical parameters of human blood belonging to blood groups A, B, AB & O collected from the normal persons. The parameters obser...

INTRODUCTION The rapid growth of wireless communication technologies has caused public concerns regarding the biological effects of electromagnetic radiations on human health. Some early reports indicated a wide variety of non-thermal effects of electromagnetic radiation on amphibians such as the alterations of the pattern of muscle extractions. This study is aimed at investigating the effects ...
electromagnetic waves can damage sex organs and cause hormonal disorders, and garlic isknown to reduce risk factors for various diseases. the aim of this study was to investigate theprobable effects of mobile phone radiation and the consumption of garlic on testosterone levelsand testicular changes. five groups of rats were used: control, sham (exposed to 900 mhzwavelength), experimental group ...
reviews in many countries indicate that drivers often talk on mobile (cell) phones. studies have been done on possible effects of concurrent mobile phone use on driving performance. previous studies have found that phone talking could impairs performance on simulated or instrumented driving tasks, using such measures as reaction time, following distance, and situational awareness. most of these...
Background: The use of mobile phone by children is increasing drastically. Children are likely to accumulate many years of exposure during their lives. Furthermore, as nervous systems in children are developing, children may be at a greater risk compared to adults. In this light, some scientists have suggested that the use of mobile phones should be restricted in high-risk groups such as childr...
