ABSTRACT
This paper proposes a method for making a transition between discontinuous magnetic-field limit values set by exposure standards in adjacent frequency ranges. This method is applied to the limit values set by the International Commission on Non-Ionizing Radiation Protection for static and extremely low frequency magnetic fields. In this case, both ceiling and time-weighted average values are provided for static fields, but only ceiling limits are provided for extremely low frequency fields. The proposed method of setting both types of limit values for magnetic fields between 0 and 1 Hz can contribute to achieving exposure standards that have continuity on the entire frequency spectrum. As far as it eliminates discontinuities, it will also help the implementation of regulations by eliminating some uncertainties. Therefore, it could reduce difficulties in checking compliance with standards.
