This study focused on the evaluation of the exposure of children aging from five to fourteen years to 50 Hz homogenous magnetic field uncertain orientation using stochastic dosimetry. Surrogate models allowed assessing how the variation of the orientation of the magnetic field influenced the induced electric field in each tissue of the central nervous system (CNS) and in the peripheral nervous ...

in Gaussian units, where is the electric charge density, A is the magnetic vector potential (where ∇ ·A = 0 for static fields in both the Coulomb and Lorenz gauges), E is the electric field, B is the magnetic field, V is the electric scalar potential, and J is the electric current density. The first form is due to Faraday and Maxwell, the second form is due to Poynting Thomson and Poincaré, the...

Pulsed electromagnetic fields (PEMFs) have been used extensively in bone fracture repairs and wound healing. It is accepted that the induced electric field is the dose metric. The mechanisms of interaction between weak magnetic fields and biological systems present more ambiguity than that of PEMFs since weak electric currents induced by PEMFs are believed to mediate the healing process, which ...

Mobile phone use by children and adolescents has increased considerably during the last 15 years. This has resulted in public concerns about possible adverse effects of radiofrequency electromagnetic fields generated by these devices. So far, the risk of brain tumors due to mobile phone use has not been addressed in this age group. CEFALO is an international case-control study examining the ass...

The asymptotic description of the coupled spatial and temporal evolution of a pulsed ultrawideband electromagnetic beam field as it propagates through a dispersive, attenuative material that occupies the half-space z > or = z(0) is obtained from the angular spectrum of plane waves representation. This angular-spectrum representation expresses the wave field as a superposition of both homogeneou...

Background: Previous studies have shown that exposure to electromagnetic fields produced by magnetic resonance imaging or mobile phones can lead to increased microleakage of dental amalgam.Objective: The aim of the present study was to investigate the effect of electromagnetic field of a commercial dental light cure device and a common GSM mobile phone on microleakage of amalgam restorations.Ma...

We aimed to review the findings of exposure assessment studies done in European countries on the exposure of the general public to low frequency electric and magnetic fields (EMFs) of various frequencies. The study shows that outdoor average extremely low frequency magnetic fields (ELF-MF) in public areas in urban environments range between 0.05 and 0.2 µT in terms of flux densities, but strong...
