Quasi-Static Theory for Uniaxial Chiral Omega Media
The problem of unbounded uniaxial chiral omega media in the presence of both static electric and magnetic point charges is investigated. For this purpose scalar electric and magnetic potentials in these media are introduced. Using these potentials, the corresponding electric and magnetic fields are determined. The similar problem of static electric and magnetic current sources with the goal of ...
متن کاملDoes Exposure to Static Magnetic Fields Generated by Magnetic Resonance Imaging Scanners Raise Safety Problems for Personnel?
MRI workers are occupationally exposed to static and time-varying gradient magnetic fields. While the 24-hour time-averaged exposure to static magnetic fields is about a few mT, the maximum static field strength can be as high as 500 mT during patient setup. Over the past several years, our laboratory has performed extensive experiments on the health effects of exposure of animal models and h...
متن کاملبررسی میزان مواجهه شغلی با میدان های مغناطیسی پایا واثرات بهداشتی آن در مراکز تصویر برداری تشدید مغناطیسی
Background and aim: Magnetic resonance imaging as one of the best medical scanning technique is considered to be the most important sources of static magnetic fields. The staffs of MRI ´s units frequently exposed to these static magnetic fields. This study aims to determine the occupational exposure level to mentioned field and its related health effects in MRI´s units. Methods: The occup...
متن کاملThe modeling of induced current density in eyes from static magnetic fields produce by MR scanner
Introduction: Staff and patient Movement in static magnetic field MRI scanner induces current density in the human tissues, so cause biologic effects in people. The aim of this study was the Modelling of current density induced by moving individual with different velocities in static magnetic field of magnetic resonance imaging. Materials and Methods: current ...
متن کاملThe effect of 17 days exposure to static magnetic fields on the hypothalamic-pituitary-gonadal axis in the male rat
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...
