Background Exposure to electro-magnetic fields is a risk factor for abortion. We aimed to review the relationship between exposure to magnetic fields during pregnancy and the risk of abortion. Materials and Methods: Two independent researchers screened the articles with related keywords including: "Radiofrequency", "RF", "RF-EMFs",...
In the present study, we examined the effects of extremely low-frequency (ELF) electromagnetic fields on morphine-induced conditioned place preferences in rats. During the conditioning phase (12 days), three groups of rats were placed in a sensory cue-defined environment paired with morphine (10mg/kg, i.p.) following exposure to either 20 Hz (1.80 mT) or 50 Hz (2.20 mT) or sham electromagnetic ...
Three years after the first interlaboratory comparison programme (ILC) for extremely low frequency electromagnetic fields (ELF EMF), twelve participating laboratories measured the values of electric and magnetic fields including frequency in three stages at specified positions and distances from the field sources. This paper presents the measurements procedure, the results and their evaluation ...
