BACKGROUND The World Health Organization has emphasized the need for research into the possible effects of radiofrequency fields in children. We examined the association between prenatal and postnatal exposure to cell phones and behavioral problems in young children. METHODS Mothers were recruited to the Danish National Birth Cohort early in pregnancy. When the children of those pregnancies r...

Over the past decade, the use of mobile phones has increased significantly. However, with every technological development comes some element of health concern, and cell phones are no exception. Recently, various studies have highlighted the negative effects of cell phone exposure on human health, and concerns about possible hazards related to cell phone exposure have been growing. This is a com...

Abstract Background and Objectives: Incidents related to electromagnetic interference with medical devices have been reported over the past decades. It has also been indicated that the microwave radiation emitted from mobile phones interferes with the operation of medical devices therefore, this study aimed at testing the interference by GSM mobile phones with cell counters. Material and Method...

Introduction: There are general concerns about the hazardous impacts of the cell phones radiation on the human health. In this study, the structural and biochemical changes of the mice kidney were assessed after cell phone exposure in. Materials and methods: A total of 40 Balb/C mice were randomly divided into the control and experimental groups. The experimental group exposed to cell phon...

Background: Over the past several years, the rapidly increasing use of mobile phones has raised global concerns about the biological effects of exposure to radiofrequency (RF) radiation. Numerous studies have shown that exposure to electromagnetic fields (EMFs) can be associated with effects on the nervous, endocrine, immune, cardiovascular, hematopoietic and ocular systems. In spite of genetic...

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 Potential health effects of cell phone use in children have not been adequately examined. As children are using cell phones at earlier ages, research among this group has been identified as the highest priority by both national and international organisations. The authors previously reported results from the Danish National Birth Cohort (DNBC), which looked at prenatal and postnatal ...
