公众在使用手机和WiFi通信技术的同时，也暴露于一个叠加的复合射频电磁场中。手机和基站辐射的生物学效应研究较多，但其和WiFi辐射叠加长期暴露产生的生物学效应鲜有研究。通常在生物结构未检测到改变之前，动物已经表现为子代行为发育异常或行为功能障碍。大鼠出生前（孕期）暴露于手机与WiFi低强度射频电磁辐射，通过对孕鼠生殖过程、F1代大鼠早期生理和神经行为发育的观测，及操作行为功能、空间学习记忆和感觉门控P50的测试，探讨本实验条件下射频电磁场对仔鼠早期中枢神经系统可能存在的生物学效应或健康危害，为射频电磁场暴露的风险评估和标准更新提供新依据。

With the development of mobile Internet, wireless access networks has been widely covered in the public environment. However, the public are generally exposed to combined frequency electromagnetic fields even with a more convenient and efficient communication. European scholars reported that mobile phone signal and WiFi signal are the main reasons for microenvironment electromagnetic radiation. Besides, the radiofrequency radiation from WiFi and mobile phone will not only cause insomnia or interrupted sleep but also the change of brain waves. At 2005 the World Health Organization International Workshop on Exposures and Health Consequences of Base Stations and Wireless Networks, more attention was drawn to the health problems led by the radiation superposition of mobile wireless network and other radio frequency devices at home and office.With the advancement of International Electromagnetic Project run by the World Health Organization the mobile phone radiation has been regarded by its subordinate International Agency for Research on Cancers as the potential cancer causing factor. In fact, the research at present on health effects produced by the superposition of electromagnetic radiation of mobile phone and WiFi still remains to be studied further. Our program generally focuses on what the pregnant rats exposed to mobile phones with WiFi magnetic radiation will consequently react. Based on the examination of their behavioral function and the sensory gating P50, research has been conducted on the damaged brain cognitive function and its mechanism of action because of the superposition of low intensity electromagnetic radiation effects. Through evaluation of the health effects produced by two kinds of superposition of the electromagnetic radiation, new scientific basis has been found and established for risk assessment and standards setting of radio frequency electromagnetic radiation.
