电器电磁辐射对人的影响及保护措施的研究

Effect of Electromagnetic Radiation from Home Electrical Equipments and Protective Measures

任何带电体周围都存在着电场,周期变化的电场就会产生周期变化的磁场,就存在电磁波,产生电磁辐射,过量的电磁辐射造成电磁污染。一些发射设备、微波设备、家用电器、现代办公设备、高压输配电系统等,都有可能造成电磁污染。一般而言,长波对人体的影响较弱,波长越短频率越高,对人体影响越大,微波的影响最为突出。彩电、家用电脑所发出的电磁波属于超短波,微波炉、通讯类手机等在使用时所发射的电磁波属于微波范畴。微机的大量使用为社会创造了巨大的财富,但是,它同时也对用户的身体健康造成了损害。一般用户对这个问题知道得不多,没有引起足够的重视。在此分析了电器如何产生电磁辐射及其对人类的危害,并对它的防护做了简单介绍。

Any electric equipment has electric field around it.The periodic change electric field produces the periodic change magnetic field,and has electromagnetic wave and electromagnetic radiation.Electromagnetic pollution is caused by excessive electromagnetic radiation.Generally speaking,The generate electromagnetic radiation is harmful to human beings,espetially microwaves,short waves and ultrashort waves.The wave type and classification of the domestic appliance are analyzed.The protective measures are introduced.
