Introduction: The present study aimed to present a numerical analysis of the penetration depth,  specific absorption rate (SAR), and temperature rise in various eye tissues with varying distance between radiation source and exposed human eye tissues (i.e., cornea, posterior chamber, anterior chamber, lens, sclera, vitreous humor, and iris) at frequencies of 900 and1800 MHz. Materials and Method...

Introduction: Cell phone usage during driving has become a threat to traffic safety. This study aimed to determine the effectiveness of an educational program based on the health belief model to reduce cell phone usage during driving in taxi drivers of Tuyserkan.  Materials and Methods: In this quasi-experimental study, 110 taxi drivers younger than 35 years were randomly divided into t...

Myth: Cell phones and other similar technology increase the risk of brain tumors. Answer: Lawsuits and news headlines have fueled the myth that cell phones cause cancer, particularly brain cancer. According to a survey by Gansler (2008), about 30% of Americans believe the myth. Cell phones are clearly visible in society. Statistics show that 79% of the U.S. population and 90% of European and As...

background: whether exposure to common electromagnetic fields affects human health adversely has been a controversial issue. the main goal of this study was to assess the role of 900 mhz microwave radiations with different specific absorption rates (sars), emitted from some widely used cell phones, on the induction of adaptive response in male balb/c mice after receiving a lethal dose of gamma ...

Today, cell phone technology is an integral part of everyday life and its use is not only restricted to voice conversations but also conveying news, high resolution pictures and internet. However, these advances in technology are accompanied by progressive boost in the intensity and frequency of the emitted electromagnetic waves without consideration of their health consequences. Our bodies act...

Cancer of the breast is the second leading cause of cancer death among women worldwide. The majority of cancer of the breast cases (95%) is not hereditary. Can long-term cell phone use be linked to breast cancer? It is unlikely that electromagnetic radiation is involved, but it could possibly be due to the generated heat (cell phones only occasionally transmit when people are not talking on the...

background: radiation-induced bystander effect is a response which results in damage in non-irradiated cells in response to signals from the irradiated cells. the aim of the present study was to investigate microwave-induced bystander effect from a gsm mobile phone simulator on induction of apoptosis in jurkat cell line. materials and methods: jurkat cells were divided into three groups of non-...

Background: Induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. An incoherent noise field is supposed to suppress the bioeffects of regular RF electromagnetic fields. The purpose of this study was to investigate the effect of GSM mobile phone-induced radiofrequency (RF) on the induction of oxidative stress in SP2/0 cell line. Materials and Meth...

We have examined whether non-thermal exposures of cultures of the human endothelial cell line EA.hy926 to 900 MHz GSM mobile phone microwave radiation could activate stress response. Results obtained demonstrate that 1-hour non-thermal exposure of EA.hy926 cells changes the phosphorylation status of numerous, yet largely unidentified, proteins. One of the affected proteins was identified as hea...
