Background: Expansion of the use of magnetic fields in metals, mining, transport, research, and medicine industries has led to a discussion about the effects of magnetic fields and whether their strength is negligible. The aim of this study was to investigate the effects of magnetic field on the viability and proliferation rate of HeLa cells. Materials and methods: We studied the effects of ma...

recently, the hypothesis in which memory and information would be stored as magnetic forms in astrocytes is expanding and neuromagnetic interactions between neurons and neighboring astrocytes in neocortex have potential to be the basis of memory formation. it has been proposed that all sorts of information may be maintained in form of neuronal activity-associated magnetic fields (naamfs) and th...

The rapid development of technologies using static magnetic fields particularly in medicine has resulted in an increase in human exposure to very high static magnetic fields. ICNIRP is the internationally recognised body that sets guidelines for protection against adverse health effects of non-ionizing radiation including static magnetic fields. It has recently published guidelines on limiting ...

Introduction: One of the pollutants that is developing in human life day by day is Magnetic field. In modern urban transport systems, diesel motors have been replaced with electric motors, working with alternating and direct currents, and leading to occupational exposure of drivers with magnetic fields. This study aimed to determine the urban train's drivers exposure with static magnetic fields...

Power stations produce a range of magnetic fields more than 20 mT which are harmful to those working or living around them. Several investigators have reported an increased health risk due to exposure to electric and magnetic fields (EMF) at 50 and 60 Hz. Several studies have been reported especially with increased tumor incidence, effects on reproduction and development, and neural and behavio...
