Abstract

Purpose: Wireless communication has become an integral part of our lives. The growing number of antennas in our environment and the expanding use of mobile phones (MPs) are increasing the population's exposure to electromagnetic fields. The present study aimed to examine the potential impact of MPs radiofrequency electromagnetic fields (RF-EMF) exposure on the brainwaves of the resting electroencephalogram (EEG) in humans.

Materials and methods: Twenty-one healthy volunteers were exposed to Global System for Mobile communications (GSM) signal at 900 MHz MP RF-EMF. The maximum specific absorption rate (SAR) of the MP averaged on 10 g tissue and 1 g tissue were measured at 0.49 W/kg, 0.70 W/kg, respectively.

Results: Results showed that while delta and beta rhythms of resting EEG were not affected, theta brainwaves were significantly modulated during exposure to RF-EMF related to MPs. For the first time, it was shown that this modulation is dependent on the eye condition, i.e. closed or open.

Conclusions: This study strongly suggests that acute exposure to RF-EMF alters the EEG theta rhythm at rest. Long-term exposure studies are required to explore the effect of this disruption in high-risk or sensitive populations.

人静息脑电图中的ta波段脑电波由手机射频调制。

目的：无线通信已经成为我们生活中不可或缺的一部分。在我们的环境中，天线数量的不断增加和移动电话（MP）的不断使用正在增加人们对电磁场的暴露。本研究旨在研究MP射频电磁场（RF-EMF）暴露对人类静息脑电图（EEG）脑电波的潜在影响。材料和方法：21名健康志愿者暴露于900 MHz MP RF-EMF。MP的最大比吸收率（SAR）在10 g组织和1 g组织在0.49 W/kg，0.70 W/kg。结果：结果显示，虽然静息脑电图的δ和β节律不受影响，但在暴露于与MP相关的RF-EMF期间，θ脑电波受到显著调制。研究首次表明，这种调节取决于眼睛的状况，即闭着还是睁开。结论：这项研究强烈表明，急性暴露于RF-EMF会改变静息时的EEGθ节律。需要进行长期暴露研究，以探索这种破坏对高危或敏感人群的影响。

期刊介绍： The International Journal of Radiation Biology publishes original papers, reviews, current topic articles, technical notes/reports, and meeting reports on the effects of ionizing, UV and visible radiation, accelerated particles, electromagnetic fields, ultrasound, heat and related modalities. The focus is on the biological effects of such radiations: from radiation chemistry to the spectrum of responses of living organisms and underlying mechanisms, including genetic abnormalities, repair phenomena, cell death, dose modifying agents and tissue responses. Application of basic studies to medical uses of radiation extends the coverage to practical problems such as physical and chemical adjuvants which improve the effectiveness of radiation in cancer therapy. Assessment of the hazards of low doses of radiation is also considered.
