Possible health risk of electromagnetic fields

Abstract

Electromagnetic field (EMF) is a kind of radiation and is emitted to environment from some medical diagnostic equipment, radio and television, communication devices such as cell phones, and other electrical appliances. It can have some risks to biological systems. There are some published documents on the possible human health risks of it including epidemiologic, in vivo, and in vitro studies. This review article focuses on the advers health effects of electromagnetic fields on reproductive and developmental system, psychological system, nervous system, genotoxic effects, carcinogenesis, ear and vestibular system, ocular system, melatonin production and circadian rhythms. Although there are some studies which indicated some possible effects on these physiological systems, the data is limited to reach exact conclusion. Further studies are needed to prove safety and biological effects of EMF.
