To investigate the influence of radiofrequency electromagnetic fields (EMFs) of cellular phone GSM signals on human sleep electroencephalographic (EEG) pattern, all-night polysomnographies of 24 healthy male subjects were recorded, both with and without exposure to a circular polarized EMF (900 MHz, pulsed with a frequency of 217 Hz, pulse width 577 micros, power flux density 0.2 W/m2. Suppression of rapid eye movement (REM) sleep as well as a sleep-inducing effect under field exposure did not reach statistical significance, so that previous results indicating alterations of these sleep parameters could not be replicated. Spectral power analysis also did not reveal any alterations of the EEG rhythms during EMF exposure. The failure to confirm our previous results might be due to dose-dependent effects of the EMF on the human sleep profile.
为研究手机GSM信号的射频电磁场（EMF）对人类睡眠脑电图（EEG）模式的影响，记录了24名健康男性受试者在暴露于圆极化EMF（900MHz，频率为217Hz脉冲，脉冲宽度577微秒，功率通量密度0.2W/m²）和未暴露情况下的整夜多导睡眠图。快速眼动（REM）睡眠的抑制以及暴露于该场下的助眠效果均未达到统计学显著性，因此无法重复之前表明这些睡眠参数发生改变的结果。频谱功率分析也未揭示EMF暴露期间EEG节律的任何改变。未能证实我们之前的结果可能是由于EMF对人类睡眠状况的剂量依赖性效应。
