The paper analyses some critical situations in the assessment of the compliance with the human exposure limits to the low-frequency magnetic fields. The study is focused on non-sinusoidal and transient waveforms in the frequency range from 8 Hz to 65 kHz. It is carried out by combining measurements and numerical evaluations, starting from actual magnetic flux density behaviours. The results show that inconsistent indications of compliance with the exposure limits may arise not only because of the evaluation method adopted, but also as a result of the used time or frequency windows in relation to the investigated magnetic field waveform.
本文分析了评估低频磁场人体暴露限值合规性时的一些关键情况。该研究聚焦于8Hz至65kHz频率范围内的非正弦和瞬态波形。研究通过结合测量和数值评估展开，从实际磁通密度行为出发。结果表明，暴露限值合规性的指示不一致，不仅可能是由于采用的评估方法，还可能是由于与所研究磁场波形相关的使用时间或频率窗口。
