摘要

According to the ICNIRP guidelines [1] and the IEEE standard [2], the dominant effect of extremely-low frequency (ELF) fields on humans is nerve stimulation due to induced current in the central nerve system. Current density averaged over an area of 1 cm~2 is used as a metric of basic restriction in the ICNIRP guidelines while electric field averaged over a distance of 5 mm is used in the IEEE standard. ICNIRP has opened a draft of new guidelines for time-varying electric and magnetic fields (1 Hz to 100 kHz). According to this draft, in-situ electric field averaged over a cube with the side length of 5 mm is used as a metric instead of the current density [1]. However, a biologically reasonable averaging distance for electric field might extend from 1 to 7 mm. The purpose of the present study is to investigate the dependence of electric field induced in the nerve tissue on the averaging volume in the Japanese adult male model named 'TARO [3], respectively, for uniform ELF electric and magnetic field-exposures.
