Dear Editor,Lack of ionizing radiation and the low level energy emission from cell phones initially led to a public perception that use of mobile phones is safe. However, the dramatic increase in the use of cell phones has generated great concerns about their potential adverse effects. We have previously found no association between self-reported illness symptoms and the exposures to microwave ...

Background and Aim: Various studies indicate that increasing and complicating use of cell phones in all age groups and in both sexes is associated with aggression. Despite the widespread use of mobile phones in Iran, psychological and behavioral effects of addiction to it and the consequences have not been investigated yet. The present study aimed at determining prevalence of mobile dependency ...

Background Exposure to electro-magnetic fields is a risk factor for abortion. We aimed to review the relationship between exposure to magnetic fields during pregnancy and the risk of abortion. Materials and Methods: Two independent researchers screened the articles with related keywords including: "Radiofrequency", "RF", "RF-EMFs",...

The International Agency for Research on Cancer has classified radiofrequency radiation as possibly carcinogenic. Previous studies have focused on intracranial tumors, although the skin receives much radiation. In a nationwide cohort study, 355,701 private mobile phone subscribers in Denmark from 1987 to 1995 were followed up through 2007. We calculated incidence rate ratios (IRRs) for melanoma...

The effect of UV beam, which has been emitted from a natural or a manmade source on cells has been studied in previous studies for several times. Radiation of this beam can have different effects on DNA of the cell, cytotoxicity, the structure of cellular proteins and their mechanical properties based on radiation period or frequency. The effect of radiation of two types of beams, namely UVB an...
