Abstract

Use of the third generation mobile phone system is increasing worldwide. This is the first study to investigate the effects of the third generation system on regional cerebral blood flow (rCBF) in humans. We compared effects of the electromagnetic field (EMF) emitted from the Wideband Code Division Multiple Access (W-CDMA) cellular system versus sham control exposure on rCBF in humans. Nine healthy male volunteers participated in this study. Positron emission tomography (PET) scans were obtained before, during, and after unilateral 30 min EMF exposure. The subtraction analysis revealed no significant rCBF changes caused by the EMF conditions compared with the sham exposure, suggesting that EMF emitted by a third generation mobile phone does not affect rCBF in humans.

摘要

第三代移动电话系统在全球的使用正在增加。这是第一项研究第三代系统对人类局部脑血流量（rCBF）影响的研究。我们比较了宽带码分多址（W-CDMA）蜂窝系统发出的电磁场（EMF）与假对照暴露对人类rCBF的影响。九名健康男性志愿者参与了这项研究。在单侧30分钟EMF暴露之前、期间和之后进行了正电子发射断层扫描（PET）。减法分析显示，与假暴露相比，EMF条件未引起rCBF的显著变化，这表明第三代移动电话发出的EMF不会影响人类的rCBF。
