极低频电磁场(extremely low frequency electromagneticfields,ELF-EMFs)是频率在300Hz以下的交变电磁场,主要由电力供应设备和各类家用电器产生。该频段的波长很长,本质上是一种感应场〔1〕。国内外已经进行了大量极低频电磁场与人体健康的研究,发现极低频电磁场对神经系统、
Extremely low frequency electromagnetic fields (ELF-EMFs) are alternating electromagnetic fields with frequencies below 300 Hz, mainly generated by power supply equipment and various types of household appliances. The wavelength of this band is very long, which is essentially an inductive field [1]. At home and abroad have conducted a large number of very low frequency electromagnetic fields and human health research and found very low frequency electromagnetic field on the nervous system,
