Health effects of low frequency electromagnetic radiation

Biological effects of low frequency electromagnetic fields.

Epidemiological studies since 1979 have raised some medical and much public concern that low frequency electromagnetic fields, such as those of power-lines and in domestic and industrial electrical wiring, may have harmful biological effects. These studies are generally inconsistent, inconclusive, and difficult to replicate. Identifying biological mechanisms by which such harmful effects may oc...

Effects of Propagation on the High-frequency Electromagnetic Radiation from Low-altitude Nuclear Explosions

Low-Frequency Electromagnetic Scattering

The main result of this paper is to reduce the calculation of higher-order terms in the asymptotic expansions of the electric and magnetic elds at low frequencies to the solutions of certain canonical problems. We also provide a new and simple variational proof of the convergence of the electric and magnetic elds solutions of the scattering problem for the Maxwell equations as the frequency goe...

Public Health Impact of Extremely Low-Frequency Electromagnetic Fields

INTRODUCTION The association between exposure to extremely low-frequency electric and magnetic fields (ELF) and childhood leukemia has led to the classification of magnetic fields by the International Agency for Research on Cancer as a "possible human carcinogen." This association is regarded as the critical effect in risk assessment. Creating effective policy in light of widespread exposure an...

Effects of extremely low-frequency electromagnetic field on expression levels of some antioxidant genes in human MCF-7 cells

In the past three decades, study on the biological effects of extremely low-frequency electromagnetic fields (ELF-EMFs) has been of interest to scientists. Although the exact mechanism of its effect is not fully understood, free radical processes has been proposed as a possible mechanism. This study was designed to evaluate the effect of 50-Hz EMFs on the mRNA levels of seven antioxidant genes ...
