Natural and man-made low-frequency magnetic fields as a potential health hazard

Abstract

Is human health affected by low-frequency low-intensity environmental magnetic fields? There is much diehard evidence that it is. For this reason irregular, spectrally complex ULF (0–10 Hz) magnetic fields have recently come under scrutiny, typical of natural geomagnetic perturbations or electric transportation. Recent work shows that such fields do affect the nervous system and may even cause heart attacks.
