BACKGROUND The development of new wireless communication technologies that emit radio frequency electromagnetic fields (RF-EMF) is ongoing, but little is known about the RF-EMF exposure distribution in the general population. Previous attempts to measure personal exposure to RF-EMF have used different measurement protocols and analysis methods making comparisons between exposure situations acro...
The International EMF Project was established at WHO in 1996 to provide a forum for a coordinated international response to health issues raised by exposure to electric, magnetic and electromagnetic fields (EMF). Research on EMF has been ad hoc and in many cases uncoordinated. Unreplicated research has been placed at the same level as high quality research that establishes results in a scientif...
OBJECTIVE The present study was carried out to investigate the potential effects of extremely low-frequency electromagnetic fields (ELF-EMF) and lead acetate on some hemato-biochemical, immune and pathologic variables in mice. METHODS A total of 90 female mice were equally divided into six groups. (Gp. 1) kept as control, (Gp. 2) exposed to EMF of 2 millitesla (mT) intensity and 50 Hz frequen...
To investigate electromagnetic interference (EMI) of electromagnetic fields (EMF) from electronic article surveillance (EAS) systems with electronic implants numerical anatomical models of pacemaker patients were generated accounting for different implantation sites (left pectoral, right pectoral and abdominal) and body size. Induced interference voltages were calculated with a software package...
Electric and magnetic fields (EMFs) are indefinable regions of energy that often referred to as Radiation linked the use electricity well various natural man-made phenomena. Due continuous exposure Unexplained negative EMF, people experienced stress, anxiety, Hypoxia, even long-term result in Cancer patients. On other hand, Rudraksha seeds globally known electromagnetic due their positive heali...
Several groups of investigators have assessed the impact of electromagnetic fields(EMF) on sleep and its disorders, waking electroencephalography (EEG), and theneuroendocrine system. These studies evaluated the effects of both mobile and non-mobile telephone EMF exposure in humans and animals. The results of these studies aresummarized and discussed in this article. 1. Mobile Te...
In November, 2009, a scientific panel met in Seletun, Norway, for three days of intensive discussion on existing scientific evidence and public health implications of the unprecedented global exposures to artificial electromagnetic fields (EMF). EMF exposures (static to 300 GHz) result from the use of electric power and from wireless telecommunications technologies for voice and data transmissi...
Introduction: Prolonged exposure to electromagnetic fields (EMF) influences digestive system specially its motility. The present study was performed in order to study the effects of exposure to low frequency EMF on the adrenergic system of large intestine. Methods: In this experimental study, thirty adult male rats were divided into three groups: First group (experimental) inc...
Introduction: Breast cancer is the most common cause of cancer-related death among women. Recently, extremely low-frequency electromagnetic field (ELF-EMF) has been proposed as a new interfering agent with future therapeutic potentials. Many studies have revealed that cellular processes such as apoptosis in breast cancer are affected by ELF-EMFs. However, more researches are needed to clarify t...
Exposure to radiofrequency electromagnetic fields (RF-EMF) at the operating frequencies of different communication devices can cause various biological effects. However, there is a lack studies on oxidative stress response and genotoxicity in honey bee (Apis mellifera) after exposure RF-EMF. In this study, we investigated DNA damage larvae situated waxcomb cells, exposed modulated RF-EMF 23 Vm-...
