交流电频率大小假使超过二十万Hertz,电路的周边环境会发生高频电磁场。此电磁场的一定特点是电、磁相互驱使反应,互相作用而形成了高频电磁波,具有波的所有衍射性质。因为当代科学飞速发展,高频电磁场已较大范围用于影视、手机应用、工业发展、国防战略、天气预估、医科作业等多项领域。但由于其本身对于人体危害的双面性,越来越多的人们开始对它所产生的人体危害进行了科研调查。本文通过对某工厂高频电磁辐射防护前后的调查测试,以及对周边生活环境的观察,探讨了高频电磁场辐射对人们的危害及一定的预防保护。
If the AC frequency is larger than 200,000 Hertz, a high-frequency electromagnetic field will occur around the circuit. A certain characteristic of this electromagnetic field is that electricity and magnetism drive each other to react and interact with each other to form a high-frequency electromagnetic wave, which has all the diffraction properties of the wave. Because of the rapid development of modern science and technology, high-frequency electromagnetic fields have been used in many fields such as video and television, mobile phone applications, industrial development, national defense strategy, weather forecast and medical operations. However, due to the double nature of its own harm to human beings, more and more people are beginning to carry out scientific research on the human hazards it causes. In this paper, through the investigation of a factory before and after the high-frequency electromagnetic radiation protection and observation of the living environment around the high-frequency electromagnetic field radiation hazards to people and a certain degree of prevention and protection.
