Since the early seventies, potential health risks from Extremely Low Frequency (ELF) exposure (50 Hz) have been extensively treated in the literature (more than 1000 references registered by WHO1, 2007). After 30 years of worldwide research, the major epidemiological output is the possible moderate increased risk (by a factor 2) of childhood leukaemia in case of a long exposure to an ambient ma...

The paper presents the human exposure assessment to Extremely Low Frequency fields (ELF) by means of the three dimensional Boundary Element Method (BEM). The formulation is based on a rather realistic representation of the human body. The paper analizes the response of the density current due to variations on the detail of the conceptual model considered. Variations on the geometry model and th...

The aim of this study was to determine whether exposure for 48 h to extremely low frequency magnetic field – ELF-MF (50 Hz, 0.5 mT) at different developmental stages of Drosophila subobscura (egg-first instar larvae and just eclosed adult) changes locomotor activity recorded for 30 min. Linear regression analysis, performed with values of successive 10-min time intervals, showed significant dif...

Extremely low frequency magnetic fields (ELF-MF) have the ability to produce a variety of behavioral and physiological changes in animals. The stomach, as the most sensitive part of the neuroendocrine organ of the gastrointestinal tract, is crucial for the initiation of a full stress response against all harmful stress. Thus, the purpose of this study was to examine whether ELF-MF stimuli induc...

Observations of extremely low frequency (ELF) radio atmospherics (sferics), the transient electromagnetic fields radiated by lightning discharges, are used to determine the current moment waveforms of vertical lightning discharges. In order to extract this information the propagation of radio atmospherics from source to receiver must be modeled accurately, especially in view of the important ro...

The aim of this study was to investigate the effect of continuous extremely low frequency magnetic fields (ELF-MFs) with a frequency of 10 Hz and an intensity of 690-720 μT on the level of 5-hydroxyindolacetic acid (5-HIAA) in adult male Wistar rats. A total of 24 adult Wistar male rats were used, and after exposure with an ELF-MF for 15 successive days, all rats in each test were anesthetized ...

Epidemiologic studies have shown the relation between exposure to extremely low frequency magnetic fields (ELF-MFs) and childhood leukemia, so assessment of children exposure levels in different environments is considered as a serious precedence. Present study aimed at determining ELF-MFs flux densities near schools in Tehran. Measurements were performed near randomly selected schools in three ...
